I took 4 RDC's & I'm using them for Passenger cars. 2 of them were originally powered w/rubberband motors. All have metal wheels w/insulated axles on 1 side. When I run 2 engines on that track I get a dead short. When I run one engine nothing shorts. I put all of the insulated wheels on the same side of all of the cars at the same time. I have the trucks marked so they won't be changed from one side to the other. Can you give me some idea's why these short.:confused:

Do they both run OK if you run them independantly? Sounds like one of them could be causing a short possibly...

You mean if I run each car by itself w/an engine? I tried that & I know the engines are not shorting out. It just happens when I run 2 engines independently of each other on the same track & one engine is pulling these 4 cars.

Check your trucks to make sure they arent in the wrong way. If you want to go through the trouble shoot me a picture of the underside of the cars with trucks and wheels the way you have them now!

Here's 2 pictures of all of the cars from the bottom.

After I turned them over I found that they all have the original metal trucks. I took some passenger car wheels & put them in the old RDC trucks. They roll real nice.

On the 3 lower cars in the picture of 4 flip 1 set of trucks around so that the screws / rivets holding the truck assembly together are on the same side. then arrange the wheels so that the insulated part is on the same side. see if that makes a difference?
