From left to right: White, Redbird, Red, Greenbird, Green, and Silver/Blue. Changeable designation signs, working head/taillights, and automatic car numbering.
My subway cars with SuperScript support aren't on the DLS yet. Andi06 wrote the SuperScript library for skin swapping, changeable designation signs, working head/taillights, and automatic car numbering.
My subway cars with SuperScript support will be available on DLS tomorrow. Please try them out and let me know how you like them before I update all of my subway cars.
NYCTA subway cars before R40 had manually operated wipers. R32 and R38 cars got electric wipers when they were rebuilt. Some subway cars like R1-R9 didn't come from factories with wipers and wipers were installed in 1950s. Making subway cars passenger-enabled requires a lot of attachment points and a few passengers included with Trainz stick their body parts outside of car bodies and into other passengers. I created my subway cars for TRS2004.
