I'm not sure what happened. I was just stuck on the train and couldn't activate anything. Strange because I wanted to see what everyone else was talking about :/
Thanks for telling us, it means the first action the player needs to take should be made a little clearer. Upon gaining movement control the door to the next car needs to be inspected, then any two windows. A little obtuse but it's to get the player to look around. Might need tweaking
