ABSTRACT:
A locomotive speed recorder system having a gear train drive operable off the drive wheel of a locomotive, in which system a pneumatically operable cam bar is provided for disengaging the gear train drive so as to de-activate the recorder during dead-head engine runs. A changeable gear train is utilized to effect drive wheel wear compensation; and a right angle drive from the drive wheel incorporates reduction gearing to reduce wear of a flexible cable connecting the right angle drive with the recorder.
