Starting work on the upper loop trestle

The upper loop will run between two raised areas of land using trestles and two bridges over the lower track. I've already positioned a connecting track between the lower level track and the upper loop, and now I'm starting work on building the first trestle and bridge.

The first issue I ran into is that I realized the track would be going right over a rock retaining wall. This wasn't going to work well for building a trestle so I decided to move the rocks back.

I pulled out all the rocks and dug back into the slope.

Rocks back in place to hold up the slope, the upper loop track now heads out into a clear area where I will build a trestle.

Next I needed to decide on the alignment of the curve.

Once I had the track aligned I could then finalize placement of the bridge, and replace the temporary PVC pipe supports with a brick pier on a gravel foundation. Likely I'll eventually cover these bricks with a more decorative siding, but for now they work fine and will keep the bridge in place.

I'm building this trestle like the last one I did, using the track as a guide and essentially building down from it to the ground. I decided on the position for each trestle bent, then measured and created a bent the right height for each position.

Here are the first six bents in position and stringers on top being weighted down until the glue sets. A few more to go to get to the bridge, but this is where I'm leaving it for today as the remaining bents were just built and I'm waiting for them to completely dry before being put in place.

A few pictures from a recent hike, starting with this wonderful patch of heartleaf arnica (Arnica cordifolia).

I was so excited to see a couple of bitterroot (Lewisia rediviva) blooms just opening up.

Western groundsel (Senecio integerrimus) is now at peak bloom.

A few robin eggs in a nest that was not very well hidden away.

New retaining wall and some more trestle repairs

My test runs pointed out a couple issues that needed fixing including a low spot on the mainline where I have a switch. I need to raise this as it's too low and results in a steep grade on the reversing loop.

A view of the problem area. I tried raising it up by piling up a lot of gravel which helped but I decided it wasn't enough.

Another view of the same area showing the low spot. The plant on the right is a native roundleaf alumroot (Heuchera cylindrica) which I added last year and it should be in bloom soon.  

To raise the track further, I decided to build a retaining wall here because of the slope. I dug out a trench along the track where it will be placed.

This new retaining wall matches the one I made earlier along a spur track, using three stakes to hold it in place. I just need to very gently and evenly pound the stakes into the ground.

Oh no! I wasn't careful enough and it got unbalanced and one section split apart.

No worries, once I leveled out the wall I glued the two pieces that had popped out back into place. Just need to let this set for 24 hours before I backfill the wall.

The partially finished wall in place. The top of the wall is higher than track level now but will be about even once I add backfill behind the wall and raise the track.

I also needed to do a little more trestle repair. I did most of the trestle repairs a few weeks ago, but a couple beams popped out of place this week after being hit by an errant Chuckit ball. 

Another quick and easy bridge repair. Chuckit ball to blame here as well.

The next day I backfilled the retaining wall, aligned the track and set it in place with ballast.

I then finished work on the spur that serves as a reverse loop for the mainline.

This is the area I'm working on next. I'm happy with the positioning of the connecting track between the mainline and the upper loop.

This switch is the connection between the upper loop and the connecting track.

One side of the upper loop will head out over a trestle here. These rocks are in the way. I'm not sure why I built this ramp so wide, so I think I'll cut back into the dirt and push the rocks back closer to the connecting track.

The upper loop will have two bridges over the lower track and I think this will be the approximate location for each bridge.

I put the bridges up on temporary supports to help me visualize where the upper loop will be heading.

The lilacs come out around the first week of May here in Spokane. I planted this one a couple years ago and this is its first year blooming.

The native serviceberry (Amelanchier alnifolia) is also in full bloom right now.

Getting the railroad up and running for spring

Spring is here again and it's time to get the railroad running. This year's report is essentially the same as last year...damage over the winter was pretty minimal with some settling as I'd expect. So time to freshen up the ballast and continue work where I left off.

Spring is definitely here. The native plants are leafing out and the lawn is a bright green.

Adding ballast along a section of new track.

This view shows the main line on the right with new ballast, the connector with the upper loop in the middle, and in the lower-left is the reverse loop for the main line.

Laying track to accurately define the curve. I'm thinking this might make a nice location for a future logging camp.

I put a fair amount of fill here to help keep the track as level as possible.

The finished curve with ballast in place.

Now that the mainline loop is complete, a short train is out for a test run.

Here the test train is crossing a switch at a low spot which I don't think is going to work well. I'll need to come up with a plan to raise the track here.

And now for a slightly longer test train with a little added weight for testing.

This section has also become a little uneven due to differential settling. I'll need to raise the track a bit just ahead of the locomotive.

And here is the test train going around the new curve. The curve is perfect and no issues for now, but I expect settling here will require maintenance next year.

Another view of the low spot. With a longer train you can clearly see it is bottoming out here.

Scene from a recent hike. With the spring weather come all the native wildflowers, including fields of arrowleaf balsamroot (Balsamorhiza sagittata)

A few early silky lupine (Lupinus sericeus) are in bloom now

Heartleaf arnica (Arnica cordifolia)

False Solomon's seal (Maianthemum racemosum)

Spring maintenance work

With the recent good weather I was able to make some progress on railroad maintenance. As I mentioned in the my last post there was relatively little damage over the winter so it was an easy task to get everything fixed up. I did some minor trestle work a couple of weeks ago and this week I returned to track alignment and ballasting.

This cribbing had dropped and shifted slightly out of place as the fill settled over the winter. I nudged it back where I needed it and then top filled with more ballast to hold the tracks in place.

This short retaining wall had started sliding down the hill so I anchored it using a few wood stakes.

I then back filled with ballast so the tracks are now secure.

Here is a reverse view of the same area.

I'm working on finalizing the alignment of the lines and setting them in place. I think I'm happy with this area and now I just need to join the track securely and add ballast. On the right is the main line. The middle track is the connector between the main line and the upper loop. And the track on the left will allow me to reverse the direction of trains on the main line.

I've finished roofing all three cabins for the railroad maintenance workers as well as the company store where workers can find overpriced organic produce and oversized novelty coffee mugs.

No new flowers in my garden yet so here is a picture from a recent hike of yellow bells (Fritillaria pudica). Locally the native wildflowers are going crazy right now and every time I go out I see something new in bloom.
