Lego Trains!

A few weeks ago I went to the annual Great Train Show at the Puyallup Fairgrounds which features layouts from many local model railroad clubs in all sizes and gauges, from tiny Z scale all the way up to 1/8 scale. The Puget Sound Garden Railway Society layout is, of course, the most important one there. But of all the other (non-garden) railroad club layouts one of my favorites is the Puget Sound Lego Train Club. Because, Lego.

The layout is constantly changing so I always see some old things and some new things. Some impressive additions this year include a few skyscrapers and even more Starbucks branding than I recall seeing before. And I left the show with a desire to go home and make my own Lego creations. Below are a few pictures from the show layout.

Lumber mills are always cool, even when the “logs” are made of acrylonitrile butadiene styrene.

Another view of the mill with a passing Starbucks train!

A very cool observatory in the forest. Astronomers using this telescope have discovered that Enceladus is actually made of ABS plastic.

A beautiful circus tent with a train encircling it.

A winter village includes a snowball fight between rebel fighters and Imperial Stormtroopers.

I had seen the Space Needle before but the three skyscrapers—Chrysler Building, Empire State Building and Willis Tower—are all new to me.

My favorite thing about this IKEA store is the inclusion of solar panels on the roof. The newly rebuilt IKEA store in Renton includes the largest solar rooftop array in the state of Washington: 3268 panels providing a max output of 1.13 megawatts.

So now that Thanksgiving has passed the dining room table has been taken over by my Lego trains. Here are a few photos of my (very small) layout. Some of the items are from sets and others are my own creations. We definitely need a larger table.

Santa’s Village includes a holiday train on display. Behind the village is a mountain that is actually a tunnel for the train. I would have made it longer but I ran out of green bricks.

The fast freight at the cargo center includes a piggyback UPS truck filled with presents.

One of my favorite things to see passing on the main line through Seattle are 737 fuselages headed to the Boeing plant in Renton. My version supports a slightly smaller airplane.

Rolling Stock: Flatcar (BN 623250)

The latest addition to the PE&A rolling stock roster is a Burlington Northern flatcar. Some assembly was required—the trucks were not attached to the car which is fine with me as I wanted to swap out the wheels and couplers so it would match my other cars. I've done this a few times before so now it only takes a few minutes.

Burlington Northern flatcar, BN 623250

The components are laid out and I'm ready to start. The provided trucks have hook-and-look couplers which I'll remove and replace with Kadee 909 truck-mounted couplers. I'm also replacing the provided plastic wheels with metal wheels.

The first step is assembling the Kadee couplers.

The next step is removing the existing couplers and then sawing off a small plastic tab from the bar which attaches to the coupler. Some coupler types use this support but it's in the way for Kadee couplers.

With the tab removed, the Kadee coupler slides right on and is attached with a single screw from below. This picture shows the completed truck in the upright position with the new metal wheels in place.

The trucks are then attached to the car body.

And the last step is attaching the decorative pieces that came with the car. In this case it only came with four step ladders and a brake wheel. There were holes drilled for grab irons but none were provided, so I found a few extras I had on hand.

In other PE&A news, I took advantage of a dry and partly sunny day to clean up the railroad right of way and test my recently converted locomotives outside. I filled up a 32 gallon container with yard waste from the train area alone, mostly dead scales from the redceder. I ran both locomotives simultaneously on the track first independently and then operating together as a consist. It is unlikely that I would operative these two locomotives together in a consist but I wanted to make sure it would work and I knew how to do it.

Next I wanted to do some load testing and see how many cars the locomotives could haul now, both independently and together as a consist. But I ran out of time so that will have to wait for another day.

Installation of Airwire G3 in AristoCraft U25B

With the successful conversion of my NW2 complete, it was time to move on to BN 5406, my AristoCraft U25B. The decoder I installed was an AirWire G3 which is their generic decoder for use on most locomotives that are not manufactured by USA Trains. Unlike the NW2 install where I was following an instruction manual designed specifically for that locomotive, here it was up to me to figure out exactly what to do and where and how to install the decoder card. Fortunately my previous installation gave me the confidence that I could do it.

Removing the existing wiring was straightforward and I found it especially satisfying to disconnect the power pickup leads, given how much trouble I had with them earlier. I kept the original switches behind the back door so I could use one of them as an on/off switch. I also removed the smoke generator as I wasn't using it, it appeared the blower fan was no longer working, and it was taking up space that I wanted to free up.

The most difficult part was figuring out how to mount the board. Unlike the board for my NW2, this one didn't have any holes for mounting screws. And the board was so small and tightly packed that I couldn't see any safe place to drill holes. The instruction manual suggests somehow mounting the board vertically to allow air flow, but this locomotive doesn't have enough vertical clearance to allow that. I didn't want to lay it flat on the floor either, so I decided to build brackets that would hold it above the floor at an angle so it would still get some air circulation. I don't know if this is the best solution but I think it will do for now.

Both locomotives are now operational on battery power and I've done some testing inside, but I need to get outside once we have some nice weather and do some real world testing. I'll be able to operate both of them from the same remote control and should be able to operate them in tandem as a consist. I also want to do load testing and see how much they can pull now.

A view of the as-is wiring, some of which was original and some of it modified by the previous owner.

After removing most of the existing wiring I decided on a location for the decoder.

The decoder after wires were attached. The blue/green wire pairs provide power to the trucks. The red/black pair on the left disappearing through the floor is the power cable that will connect with the battery car. And the other wires in the upper right go to the front cab/headlight/number board and to the rear headlight/number board.

Since I had to dismantle the cab anyway, I took the opportunity to clean the interior so the locomotive engineer will stop complaining about all the dust.
When I was testing I noticed the interior cab light was working but the headlight was not. There was some corrosion around the wire connectors so I cleaned it up and replaced some of the wire.

Cab reassembled and mounted back in place.

A happy engineer with a clean cab and a working headlight.

Solution I came up with to hold the decoder in place, at least for now. We'll see how well this works.

Battery car complete

This weekend I finished assembling the battery car and thought I would post a few pictures. I used pieces of 3/8" right-angle styrene cut to the length and width of the battery to create a cradle. This will prevent the battery from moving around while the train is in motion, and the cradle isn't very high so I can easily get the battery in and out of position through the boxcar door.

At first I thought I would use a PVC cement to attach the styrene to the car floor, but given how rough the floor surface is, I thought that Scotch double-sided mounting tape would probably work better. The cradle is centered so the weight is evenly split between the two trucks.

I will be retrofitting a second battery car but haven't decided which car I will use. In the meantime, an AirWire G3 decoder just arrived in the mail today so my next project will be converting my BN locomotive, an AristoCraft U25B, to remote control. This will be a bit more challenging that the NW2 conversion.

Work in progress, cutting right-angle styrene pieces to fit the dimensions of the battery.

Styrene pieces are secured in place and the battery fits snugly.

Conversion of UP NW2 to radio control battery power

I finally had the components together to convert my first locomotive to battery power. As I mentioned in a previous post, I decided to go with AirWire for the decoder and remote control. The AirWire catalog includes a series of decoders that are specifically designed for several USA Train models, so I thought starting with my UP NW2 from USA Trains would be a good idea.

For battery power I decided to go with Makita 18V batteries. I wanted to get a couple of big 5.0Ah batteries and I started looking online to compare prices. I ended up finding a tool set at Home Depot that was about 50% off, so for the price of what I was expecting to pay for two batteries and a charger, I also got a couple of new power tools. Both of which I've already put to use over the weekend.

The battery will not ride on the locomotive but in a trailing battery car. I'm using one of my BN boxcars as it has nice wide doors so I can easily slip the battery in and out. Eventually I'll need another battery car so I can run two locomotive simultaneously.

UP NW2 and BN boxcar in the shop ready for some major work.

The decoder kit includes two new circuit boards and a very detailed installation guide.

This is the main circuit board which receives and decodes the radio signal and controls the motors and lights.

Super fast double charger!
I'm connecting the batteries using a replacement Makita battery terminal.

View of the shop during disassembly.

View inside the hood prior to conversion. I had not been under the hood of my NW2 yet so I was surprised how many more wires there were compared to my U25B.

Disassembly was a bit more difficult than I was expecting. The screws were very tight and I ended up stripping a couple of them that were a big pain to remove. But things got easier once I got everything disassembled, as I was then just following the step-by-step instructions in the manual. My NW2 has some slight differences from the one AirWire used for their instruction manual, so I did have to improvise a little bit at times. Also, as I was using an external battery I had to come up with a solution for how to run wires from the hood circuit board out the back of the locomotive.

Once all the wires were hooked up I needed to conduct a power test to make sure everything was operational. I connected the battery, turned on the power switch, and there was a small pop and a cloud of smoke. I immediately disconnected the power as something was terribly wrong. My first thought is that I had just fried the circuit board. But fortunately the source of the smoke was the power cable. I had reused a plug that had been removed from the locomotive as it wasn't needed anymore, and upon close inspection I realized that the red/black wires on this plug were the reverse of what I needed, so I had accidentally crossed the polarity of the battery. The wires attached to that plug were also a smaller gauge, probably smaller than I should have been using, and so that thin wire is what had overheated and caused the plastic coating to burn off.

I removed the damaged section, got a different plug with a heavier gauge wire and checked twice to make sure the polarity was correct, and reattached it. I nervously hooked the power back up and this time was rewarded with a green power light and a happy little beep. I ran through the various tests and everything was working as expected. I was very fortunate that the wire had served as a circuit breaker and the board was unharmed.

Circuit board has been mounted and wires are reconnected, prior to hooking up the power.

I was planning to drill a hole at the back of the locomotive to run the power cable out. But then I noticed there were two small holes hidden under a step below the cab door, so I used them for the two wires.

I wanted to do an actual track test before closing up the locomotive, so I took it outside and got a gondola out of the garage to temporarily hold the battery. It was so exciting to see it zip around the track while I was testing out my new remote. After I was satisfied with the performance, I finished closing up the locomotive and reattaching the decorative pieces.

Then it was on to the battery car. Not much to do here compared to the locomotive, as I just need to decide how to hold the battery and run the power cable out the front end of the car. I was not able to complete it today as I'm waiting for some supplies to arrive, and hopefully I'll get it done next weekend.

Out for a test run, with the battery just sitting in an open hopper

The battery will sit in the middle of the box car so it can be accessed from the center doors. I need to create a cradle to hold the battery in place so it doesn't slide around while the train is in motion. I wasn't able to complete that step today as I'm still waiting for the materials to arrive.

To Tacoma by Rail

Another train related activity from earlier this year I had not written about yet was a day trip down to Tacoma by rail. I knew this was going to be a long post as I had so much to cover so I put it aside until I had some time. Fortunately I had made some notes to help me remember what I saw.

Sound Transit began running Sounder commuter trains between Tacoma and Seattle 17 years ago and the service has continuously grown over that time, often struggling to keep up with the growing demand. But I’m embarrassed to say that I had never been on a Sounder train before this year, as until recently they weren’t of that much use to those of us living in Seattle.

Sound Transit 901, an EMD 59PHI, ready to head south to Tacoma. This is one of the oldest locomotives in the fleet, purchased in 1999 to initiate service. These locomotives typically pull trains of seven bi-level coaches built by Bombardier.
King Street Station, built 1904–1906 by the Northern Pacific and the Great Northern.

At first the commuter trains only ran in the direction of the primary commute -- into Seattle in the morning and out of Seattle in the evening. More recently, Sound Transit “reverse commute” trains operating in the other direction were introduced, and now there are three trains running from Seattle to Tacoma each morning, allowing me to go down to Tacoma for the day and back in the afternoon. There have always been plenty of bus options that allow me to do the same thing, but the point of this trip was to use as much rail as possible – Sounder (commuter rail), Link Light Rail (Seattle), and Tacoma Link (usually called light rail, but it's actually a tram).

There is still very little customer demand for the “reverse commute” trains – the real purpose is to send a train back down to Tacoma after its first run in the morning in order to pick up a second load of passengers headed to Seattle. But rather than just repositioning the trains on deadhead runs it makes sense to use them as revenue trains in both directions. Sounder commuter trains now carry about 17,000 people per weekday. And while the trains coming into Seattle are packed to the gills, trains heading out in the morning have very light loads.

I've walked by here multiple times before but this was my first time turning right and heading down to the Sounder platform.

The train uses BNSF track between Seattle and Tacoma, a route jointly built by Northern Pacific and by a local company called the Puget Sound Shore Railroad Company in 1883-84 which met up about halfway between the two cities. In the fall of 1883 there were 1,400 Chinese working on this line—more about that later in this post. The first Northern Pacific train ran between Tacoma and Seattle on June 17, 1884 and the first regularly scheduled runs started three weeks later, taking 3 hours and 25 minutes and costing $1, the equivalent of about $25 in 2017. Today's Sounder train takes just under one hour and costs $5.25. I may be using a 133-year-old route, but the experience has improved a bit.

Detail of a map from 1900 showing the southern half of the Northern Pacific route to Tacoma. Auburn, Sumner and Puyallup were stops along the way for Northern Pacific trains and they are again today for Sounder trains. The Milwaukee Road route had not been built yet so this map is missing the last half-mile of the Sounder route into Tacoma.
Travel by train means you get to see things you just can’t see from a road, like some views of the Duwamish river that are not accessible by car, and the section of track between Sumner and Tacoma that winds through an area still primarily in agricultural production.

When arriving in Tacoma, the train switches over to track originally owned by the Milwaukee Road for the last half mile. The Sounder station is in an old Milwaukee Road warehouse. There was a lot of construction going on around the station as new tracks are being added and platforms are being extended as Amtrak will begin using it later this year, thanks to a multi-year WSDOT Tacoma Bypass project that is refurbishing an old rail route between Tacoma and the Nisqually river that will allow passenger trains to avoid the congestion and slow track speeds along the BNSF route through Tacoma. More information on that project can be found here.

Platform extension work at the Tacoma Dome Station in preparation for Amtrak.

After disembarking the Sounder train, it's just a short walk across the street to catch the Tacoma Link, the light rail line operated by Sound Transit connecting the train station with downtown. The current line is a very short 1.6 miles long, but soon will be extended by an additional 2.4 miles.

Tacoma Link uses bi-directional trams manufactured by Škoda, the same type used by the Portland Streetcar system.

The main draw in Tacoma for this trip was an exhibit at the Tacoma Art Museum of works by Abby Williams Hill, a painter who spent much of her life in the Pacific Northwest. In the early 20th century she was hired once by Great Northern and three times by Northern Pacific to paint images that the railroads could use for promotional purposes, including exhibition at various world’s fairs in the early part of the century. She spent four summers hiking and painting for the railroads, in the North Cascades, northern Rockies and Yellowstone National Park. Many of her paintings, as well as many letters, diaries and other personal items are now held by the University of Puget Sound, which loaned the material to the Tacoma Art Museum for the exhibit. None of the pictures below really do the artwork justice—you need to visit to see the art in person.

I didn’t realize until I arrived that the TAM also had another railroad related exhibit on view. This one was a collection of works by contemporary artist Zhi Lin who was exploring the role of Chinese laborers who helped build railroads in the western U.S. in the latter half of the 19th century. Tens of thousands of Chinese laborers worked on railroads—the exact number is not know but it was at least 30,000. Yet less than a thousand of those people are known today by name, mostly from railroad payrolls that had survived. The purpose of his art is to give a voice to these unnamed laborers.

One of the pieces in the exhibit was a video projected on a wall in the gallery showing an annual reenactment of the golden spike ceremony at Promontory Point, Utah, recorded from the reverse side and at a distance, symbolizing the view that the Chinese laborers would have had. At the base of the projection area is a sloped layer of track ballast.

A close-up view of the ballast. Many of the rocks had names of Chinese laborers, some in Roman script, others in Chinese script. After this exhibit closes, the ballast will be incorporated into a display at the Chinese Reconciliation Garden.

Also in the exhibit were a number of watercolors of various contemporary scenes around Tacoma that have historic significance, in this case the contemporary site of the Chinese Reconciliation Garden. Prominent in the foreground is the BNSF track, originally built by Chinese laborers for the Northern Pacific.

Additionally, there were some pieces the artist had created that specifically explored the 1885 expulsion of Chinese from Tacoma. The centerpiece is a 20-foot scroll depicting the forced march of all the Chinese residents of Tacoma (about 200) down Pacific Avenue and then along the tracks of the Northern Pacific line out of town. The line of Chinese surrounded by men with guns and horses forcing them to leave are juxtaposed on a background showing a contemporary view of Tacoma. And the very middle of the drawing is the Tacoma Art Museum where you, the viewer, are looking at the artwork. A very clear reminder that we are always surrounded by history that is very much tied to place. Some would say that the ghosts of the past always surround us, but I prefer to think that we are living in both the past and the present simultaneously.

Detail from the artwork showing the expulsion of the Chinese from Tacoma, here coming down Pacific Avenue and turning uphill to follow the Northern Pacific line out of town. In the lower part of the picture is the Tacoma Art Museum. And the tracks in the image are not historic but the contemporary tracks for Tacoma Link.

This image provides a detail of a mid-1880's map that the artist used while conducting research for this project. The pink line highlights the path of exodus along the Northern Pacific track. Where the yellow and pink lines converge is the intersection illustrated in the artwork above, and the site of the Tacoma Art Museum today. 

This is a contemporary view of the old Northern Pacific right-of-way, just uphill from the intersection. Today this is a pedestrian walkway through the University of Washington Tacoma campus. Some sections of track have been preserved along the pathway as a visible link to the past.

After that exhibit a logical next destination would have been the Tacoma Chinese Reconciliation Garden along the waterfront. Getting to Tacoma on public transit is very easy, but getting around Tacoma is not so much, as city bus routes may only run once per hour. So I decided the garden would wait for another day when I had a car, and instead I thought I would go to the Foss Waterway Seaport, only about a mile away. Using Tacoma Link cut that walking distance in half.

The Foss Waterway Seaport occupies the last surviving section of what was once a quarter-mile long grain storage warehouse along the waterfront. Northern Pacific trains would deliver grain on one side of the warehouse and it would be loaded out the other side onto boats. Most of the waterfront warehouses from this era have been torn down, burned down, or literally fallen into the water. Saving this last remaining section and making it safe for occupation was a big endeavor, which included replacing all the wooden truss supports underneath the building with concrete piers. The roof is held up using a modified Howe truss design that incorporate 150-foot long single piece bottom truss chords. Each one came from a single Douglas fir, a resource that can no longer be found.

The building had plaques on two sides commemorating its status on the National Register of Historic Places.

A view of the enormous roof trusses. The bottom truss chord of each one came from a single tree.

Most of the museum focuses on past and present waterfront activities—put another way, it’s mostly about boats. But there is one area of the museum that is focused on the trains that turned Tacoma into a city and another section that talked about the original warehouse activities. The museum is adjacent to Half Moon Yard, originally a near-shore tidal area between the NP track and the cliff that was filled in to create a flat area for a classification and storage yard. It is still in use today by BNSF. And towering up above the museum and yard are two significant structures— the old Northern Pacific division headquarters completed in 1888 (featuring a beautiful four-story circular tower) and the old Tacoma city hall completed in 1893 (with a beautiful Italianate clocktower).

The train section of the museum includes an HO-scale display depicting Half Moon Yard and the surrounding area. And there was also an interactive G-scale display, but unfortunately it wasn’t working the day I visited.

Not a very good picture, but this provides a view from the museum looking up the hill toward Tacoma. BNSF grain hoppers are sitting in the Half Moon Yard, and up above are the old Northern Pacific headquarters and the old City Hall behind it. Sadly, freeway ramps built around 1990 now slice through the view.

The HO-scale display of Half Moon Yard in the mid-20th century. The Balfour Dock building is the structure in the lower right-hand corner of the building. No freeway ramps here! 

For reference, here is a similar view captured from Google Earth that shows the building, Half Moon Yard, part of downtown Tacoma, and the ugly freeway ramps.

The final stop on my Tacoma trip was a visit to the Washington State History Museum. There were no train-related special exhibits during this visit, but a visit to this museum isn’t complete without a stop by the HO-scale layout on the top floor which depicts the Tacoma waterfront in the early 20th century. Interestingly, while this model provides great detail to certain parts of the waterfront—in some sections you can even identify every street and building by name—the section of waterfront I was at earlier in the afternoon is skipped over. That’s to be expected as all model railroad layouts have to limit their focus due to space constraints, and I suppose that it’s not really needed as the Foss Waterway Seaport has such a great layout capturing Half Moon Yard in detail.

I arrived back at the Tacoma Dome Station to catch a northbound Sounder train just as the first southbound train of the afternoon from Seattle was arriving. Hundreds of people got off; a few dozen of us got on for the return trip up to Seattle. And arriving at King Street Station we of course saw the opposite—a few dozen of us getting off had to squeeze our way through hundreds of commuters trying to get on. From King Street Station I was about a half-mile from the bus stop I wanted for my return home and my app showed that a bus would be there in about 12 minutes. I thought I might be able to walk there if I hurried and the stoplights happened to be in my favor, but my feet were tired after a long day of walking. So instead I walked just a few hundred feet over to the International District station where I caught a northbound Link Light Rail train that dropped me off about a block from my bus stop. I arrived just as the bus was pulling up for my final leg home. Perfect timing!
