DCC and "Seasoned" Brass Locomotives

[doctorwayne]

I'm not very conversant on DCC, but if some of your older locos are driven directly off the motor shaft (many were) and use a steel worm with a brass worm gear (it was often also the final drive gear, directly on the driver's axle), then you'll have a direct connection between the track and the motor. A possible fix would be an idler-type gearbox, with plastic gears.
