Locomotive Loses Power

[Cody J]

Can Anyone Think of a reason why my locomotive loses power on some parts of my brothers track but my brothers locomotive doesnt lose power.  When I put my engine on my track it doesnt lose power?

Two things come to mind quickly.1- Motor needs oil ( very sparsely applied very important. 2- wheels not clean. And yes, more details than " my locomotive "

Its a Red & Grat Santa Fe-END GP40 Locomotive(its the one that comes with the thunderbolt Train set.

Some thoughts:

Using only the rails to distribute power throught a layout could be the source of the problem. There can be significant resistance in the rail and joiners. This resistance will result in a voltage drop (speed change) in proportion to the current drawn by a locomotive. This could be why the difference in effect (speed).

If you understand the above you know why large gauge buss wires and multiple feeds provide trouble free DCC operation.

I pulled mine out of the box, never ran before. Runs fine albeit feels really light. I am guessing by now you have the issue fixed. for the record my track was cleaned with a fine grit paper ( 800 grit ) after smoothing the bumps where the rail joiners are.

Never use an abrasive, of any kind including track "erasers" to clean you track as they all pit the railhead, creating more gunk in the process.

here is the scoop. it is the power pack that comes with the set. Starts failing and causes the locomotive to sputter here and there. Happened today while running the engine. Hooked up a MRC power pack and it runs fine now.
