Hey everyone, I wanted to know what those tubes are in the front of the train? I know one of them is for connecting to another locomotive or train and helps with the brakes, and once it disconnects it stops the cars automatically. There appears to be 6 tubes, with 3 on each side. Is this for connecting to other locomotives as well? More power/strength? Also, I've seen videos of the tube snapping and it looks extremely dangerous, does anyone have experience with these? Looks like you can lose a hand if the thing pops! EDIT: Also! What is the 'base' piece called? The thing that actually holds up the train? Thank you!
