The cart won't move because you don't have a team_train_watcher entity telling the cart where to go. Also, if you open the cart's trigger_capture_area, you'll see the first control point is "cp_one", which doesn't exist. it looks like you took this from ABS prefab and deleted the capture points.
I'm pretty sure the train is killing you because it's surrounded by a trigger_hurt which was only supposed to destroy buildings. However, you are also missing the filter that tells it to only destroy buildings. Head back to the ABS prefab and copy all the logic this time, and only delete what you don't need, patching the holes they leave behind.
