Throttle Control

Proportion-Air offers a QB1/PSR assembly to provide throttle control for locomotives in a train yard. This particular application is remote controlled by an operator who is moving many trains around the yard.

While trains are in the yard, a QB1 mounted on a PSR air volume booster remotely controls the speed of a small locomotive by extending or retracting a cylinder moving the throttle. This allows the operator to connect or disconnect cars without climbing in and out of the locomotive.

The QB1/PSR assembly is used to provide higher flow rates and boost volume to the cylinder. This allows for faster reaction times…which can be important when remotely moving trains weighing up to 200 tones.
