Tried to avoid the procrastination (beard stroking) phase of development which was looming upon me. So far with my railways I've built baseboards and then laid the track independently. This has meant that I haven't had to have an exact track plan before building the baseboards. With this build I don't have the baseboard so I need to finalise my track plan beforehand.
Yesterday I worked through that process; placing, levelling, adjusting and swapping around blocks to enable the track plan I am after.
One consideration was to try to keep the track from being below the drip line off the Amblethorpe baseboard. This would have been easy if it was a constant width, but it varies form 40cm to 20cm to 30cm along its length. Locating points away from drips was more important.
I still can't figure out how things will work at the house end of the line. A track needs to turn off to allow a connection with the Snicketway baseboards. This requires a 90º turn in around 40cm, which is around 1st radius. This is OK for a narrow gauge, but I'll have to check that my stock is fine with that. Not that there is any set-track for On30.
At the shed end the level trackbed creates a significant rise within the landscape.
I cut the tops off the blocks at 45º to create a very narrow track bed, a common feature on American railroads.
Still work to be done on the trackbed before I can fill the gaps and create the landscape.
