hope you don't mind but i made modified versions of these coaches for use with my streamlined steam engine
hope that's not an issue

Can reskin these and refit them for a military purpose? (If i publish it then you will get full credit for making these)

This Looks Nice! It Looks Better then My Train Cars.... (MILLRAIL) They are Meant to Be Retired soon. So I may Start work on it.

It was, just i was doing it manually, one of the doors closed just fine, and i had the door latches flipped to how they were supposed to be, but the right side door, would dome to the closed position, slowly, then fling backwards to the open position snd then slowly start coming back to the closed position.

The doors aren't automatic - They're manual, just like the real thing! The 'breaker' is only the locking latch. Flip it to unlock the door, then grab the door's handle and pull hard to open the door! You may need to climb up onto the door frame first to get better leverage. Once the door is open, it'll latch in the opened position until the breaker is flipped again, setting it to latch closed.

Note, Infinite Electric will break this system. Make sure you have Infinite Electric turned off!

the doors don't want to work
