I drew this in 5 minutes because I don't get much time but you get the idea. You get 8 padded sofa like seats with each door set and a window pane bench on both sides, that it. There are 3 door sets for each trian carriage.
There isn't much stuff to go wrong, the train is slow, there are no wheels it goes 25 mph, there isn't much wind resistance. Although the train moves, there isn't much moving parts.
Time is the worst pirate.
