one of my Legacy steam engines (Daylight GS-2) stops at certain parts of my track. It always happens in the same areas of track. When this happens the front light starts blinking. When it stops I can not use the horn or the bell; and I have to adjust the throttle to get it going again; which only sometimes works. My other legacy engine has no problem (the light does not blink and it doesn't stop).
When the engine stops, I think I smell a burnt rubber odor in the area of where the train stops; but I am not sure
What could be the problem
