Model Railroad wiring help?

Question by : Model Railroad wiring help?
i have about 90 feet of track, 2 45 foot mainlines, when i run the train around, the train will slow down, sometimes to a stop, right before a power lead, i put one every 2 pieces of track. Does anybody know what is causing this, or how i can correct it?

It sounds like you have a polarity problem.
Check all the wires.

If you have one set reversed, the track will act like a resistor and cancel out the power about midway between two of the connection points,

All the wires on the outside rail should be one polarity and all the wires on the inside rail will be the other polarity.
