With TSW still not open for third parties, TSxx will be the main game for route builders for a while more.
For ScaleRail, I'd like to see 112 Lbs track and US specific hardware, i.e. closed frogs, derails, electrical locks, signals, etc.
I believe some of these were planned initially, and some have materialised in Tehachapi assets, but as a whole, there are still gaps.
Is 112 Lbs and lighter track possible? By matrix transformation you can probably reduce rail size, but what about tie spacing? Old track needs new textures for dirty ballast and crumpling ties.
Closed frogs etc mean a complete remake of the dynamic creation of track? Or is panel track (a.k.a. model railroad track pieces) an option?
