GBC- On and off the train!

HI,

This is a GBC I made (my own design) called: On and Off the Train! It takes the balls on one of two carriages around the train and drops them off at the other side without remote control!! Then they go up the conveyor and back through the track to the start. Whew! Watch the video! If you want to start the video at the close-ups, please skip the video to 2:18 minutes.

Thanks for watching
