Leicester Thumper Posted April 18, 2011 Share Posted April 18, 2011 I recenty bought a new version of a farish class 37, 37254 and its got a very strange fault. when you apply power to the loco it hums and even at fully speed it still hums and it runs ok and all works fine, is this a motor problem ? is it DC or DCC? that may have a slight difference... other than that, I would say something to do with the motor, aint been inside a new 37 with my mate yet but might be something to do with the motor brushes? unless it is a sealed unit like Dapol use.....
