Gotham Rail 3046 - EMD Speed Recorder Drive 4x - HO Scale

This is a gear driven speedometer drive, which would be used with older, drive cable operated speedometers like Barco and Chicago Pneumatic speed recorders.  These were used on just about every type of EMD locomotive from F units to SD40-2’s.  Our part has the correct offset drive mechanism mounted on a flange, which sits proud of the journal cover.

Includes 4 drive units as well as cable.
