Power source
I suggest using a 1.5V ac adapter wired into the circuit instead of a battery.

From Jason Mellard:
By the way, I got a 1.5v adapter from Radio Shack that I plugged into the wall and attached to the elevator motor. It works great. Now I can load up to 12 or 15 marbles on the track. It is a 1.5v/3.0v, 300mA AC adapter, product #273-1654B from Radio Shack. I think it was about $12.00. They have one that is only 1.5v (you can switch the one I got from 1.5v to 3.0v). That is really all you need, 3.0v is too fast. That one is probably a couple bucks cheaper. I just cut of the end that you would stick into a casette player or whatever, stripped some of the plastic off and connected the wires to the motor. You'll be able to tell if you connected the wires wrong, because the elevator will go down instead of up. Then you can just switch 'em.
