Hi, thanks for commenting

When I increase the voltage the light remains on and it runs smoothly.

I have not cleaned the locomotive or track. The locomotive and track is brand new

Hello, I was wondering if somebody could help me.
I recently bought a brand new N scale Santa Fe locomotive.  It will work for around an 1 hour and just stop on the tracks.It does not get that burning smell, but It does feel a little warm. If I increase the power it will start again. Should I return it or does it need simple maintenance?

Thanks.
