I made a train and a canyon but "forgot" to make a bridge.

If you want to make one, please use the pieces given for added difficulty, and also only use fixates to secure the bridge to the canyon walls.

As for the train, this is probably the most detailed Phun objects I`ve spent on. I based the moving parts off an example of a train, as well the freight cars have their own brakes. If you want to add more cars, copy/paste them and center the red circle into the corresponding black square coupler.

c and z are forward and backwards on speed one.
a and d is speed two.
e is forward for speed three.
b is brake.

I will be creating more cars when I get some more time.
