After SN changed from 1200 volts to 1500 volts on the trolley wire between Oakland and Sacramento the 22:55 gear ratio between the motors and axles did not change. Westinghouse 322-E motors with 36 inch wheel trucks show a top speed of 77.3 mph with 1500 volt trolley voltage and 50 amp current per motor with this gear ratio.

If you will look at the SN employee time table from Rio Vista Junction to Riverview you will find that the passenger trains had to go 52.34 mph average to stay on time. This average speed included station stops.

Obviously these cars were capable of speeds well over 60 mph. So these are not all railfan urban legends.
