Monk Subdivision - More Roadbed

 As I reassemble the splines in a slightly improved location, I have to make a few adjustments. The original splines were built when, for a short while, I envisioned to have the station in the foreground and the team track in the background for visual interest. It was a fascinating idea, but I left it alone because the foreground buildings would be a real nuisance during operation, having the team track far away behind the traffic was not optimal and the most intricate facades of the each structure would be invisible, which would be... self defeating.

This change of plan means that the outer left curve in Armagh (West) was build with some compromises due to being a passing track but the inner curve was the right radius. I cut the spline where both the main and passing track had constant radius to remove the discrepancy. To save on material, I cut away the funky old passing track easement to the turnout and only kept the inner portion that had the right 42" radius with a large sweeping easement to the turnout.

On the right corner (East), it was just a matter of matching splines

That salvaged piece of spline was then reattached to the outer track, making a beautiful constant 42" radius for the mainline, which was always the goal.

In the station area, the old splines fit perfectly

I could have saved myself some troubles and relaid the splines from scratch, but that would have meant to buy another sheet of MDF, rip it into strips and build a new series of splines. The recycling option was interesting in the measure I got my desired radius without compromising on the geometry. If such a compromise would have been required, I would have built new from the ground. Track geometry is the place where half-baked efforts and cheapskate strategies never pay of.

Monk Subdivision - Reinstalling the Roadbed

After rebuilding the bridge and adjusting it a bit, it was time to finally reinstall the roadbed aka the splines. I had carefully cut them in sections for storage a year ago to make it easier to rebuild the layout. Unfortunately, I recalled I had buil them according to a different track geometry. 2 years ago, I had in mind to have the station in the foreground and the passing track near the backdrop. However, plans have reverted back to having the depot facing people in the aisle.

A mockup always help to raise your spirit!

It shouldn't take too much work to adapt the splines since the curve radii are corrects. However, I still had to build from scratch the pesky S-curve entering the staging after Lake Therrien. This is probably the most tricky area of the layout. Since I want to run passenger cars and large steamers, I have no choice but make sure the straight transition is over 13 inches and that my curves all have a generous easement.

The track leaving the staging is a 28" radius. I wish I could use a large one, but there is a limit to what can be achieved with the staging. With this tight geometry, not mistakes can be made. So, instead of build the spline right on the layout with a part inserted into the wall and no way to really figure out the radius, I decided to draw a perfect template on a sheet on plywood, drive locating nails at regular intervals and use that as a tool to build the MDF spline. When done, I installed it temporarily and checked the alignment using Kato Unitrack curved tracks. Mind you, I was less than 1/4" out of alignment in the staging room, meaning it was well within building tolerances.

Gluing some cork before installation

Before installing the spline, I glued some cork at the end to ensure I could align the roadbed with the fiberboard in the staging. Installing the spline was a child's play, using some cardboard template to make sure the alignment was perfect.

Installed and ready to glue

All in all, this step proved to be much easier than anticipated, which was a great relief. But it also made me think about the future of the layout, my level of energy and my desire to run trains in a smooth and simpler fashion.

Reverting back to a saner and simpler staging concept

At the end of the day, my philosophy has been rehashed and tested again and again in this blog. Vince Valley just cemented my hatred of complicated wiring, how this stuff can take all the joy from the room. It also thought me the chances I will operated complicated scheduled trains are very scarce. For that reason, I removed the complicated crossover that made it possible to reverse trains. Sure, it was excellent on paper, but execution was complicated, made DCC and DC use incompatible and was a source of derailment even in the best conditions. I decided to reduce the number of available tracks, get rid of the troublesome curved turnout and have a nice and simple staging yard. Sure, trains won't be reverse, but I also have enough loco and rolling stock to stage enough trains in both directions to be happy. Wiring will be simpler and if I ever decided to do some automation, things will be far more user friendly.
