Please can someone tell me the dimensions of the following Bachmann N scale replacement motors :

P/N 50504 0-6-0/2-6-2 Motor

P/N 811xx-N81102 2-8-0 Motor

I would like to know the size of both the motor body and the drive shaft

TIA

Ron

Will it be possible to use a Digitrax DS64 stationary decoder for switches in combination with the Bachmann Dynamis DCC system?
