I am trying to run a train with 50 carriages. Of course one motor is not sufficient to pull all that weight. I have inserted a total of 8 motors into the train but the rail voltage is not powerful enough to run them at a decent speed. My question is if I put another regulator and power supply connected to the rail and operate both at the same time will I damage the motors. Obviously the 9V system was designed to draw enough power for one or two motor, so basically I'm trying to run 8 off of two regulators. It does work. If I crank the first regulator up to max and the the train hardly moves when I turn the other one up the train move off smoothly and at a nice pace.

^^Too much Lego is never enough :-)
As soon as you turn the controller in the opposite direction you're effectively reversing the voltage - it's like putting batteries together with two + or - ends connecting - it doesn't make a circuit and so just doesn't work!
