atlas alco rs32

just bought the beast, and it ran almost silently, creeping perfectly around the yard, a nest of dodgily installed turnouts.

I'm in heaven

Then, just now, I hear a scratchy humming when crank in some voltage.

the frequency of the thrumming goes up as I increase throttle.

the engine still runs very smoothly, it's just the sound that is driving me bats.

I guess I'm taking the thing back to the shop tomorrow, but if anyone has an idea what's happening, i'd be grateful to hear it.
