The Trains and Wagons don't pivot or retract when moving up slopes, perhaps add some graphics from the elevated rails mod and incorporate them into the higher tier trains, if you don't feel like you want to it's fine, I just find the way they go up a Elevated Rail Ramp is kinda janky ngl

Had a look at this, because it vexed me.

BTS does not do its own graphics so for a moment I wondered how this could even happen. All it does is creating a deep-copy of the vanilla wagon. Looking at the prototypes I saw that it copied everything but the elevated-rails stuff. Probably because it gets loaded too early.

All I had to do to fix it was declaring an optional dependency on elevated-rails inside info.json.
