A compressed air braking system for a railcar and railcar moving vehicle combination. The railcar moving vehicle comprises a modified semi-tractor configured to ride on railroad track and couple to a railcar. The railcar moving vehicle further includes means for producing compressed air at a desired pressure, means for transmitting the compressed air through an outlet conduit to the braking system of one or more coupled railcars, and brake actuation means whereby an operator may selectively release pressure in the outlet conduit to actuate the compressed air brakes of the railcar. The brake actuation means may comprise a plurality of electrically operated valves for selectively releasing pressure from the brake pipe of the connected railcar, and a multi-position electrical switch for activating the plurality of valves.
