I pushed some changes to GitHub. Please give it a try, make some wild trains, and let me know how that goes.

will do! i found a spot on my map where i could get a 56 cart train spawned in....ITS BADASS...and a massive frames sucker....but BADASS...
ive noticed -- at least on this update and my server -- it eats about 0.2-0.5 fps per traincar --- cause that 56 cart bastard ate 30fps lmao

Thanks for the update.

No, I didn't make any optimizations. Not sure if there are any that I could do. It probably depends on how many engines are on the train.
