Some of Our Clients
The Joule Piston Retarder is used in Class 1 railroads across North America such as Union Pacific Railroad, Canadian National, and BNSF. The retarders are also in use in South Africa and Mozambique.
Joule retarders are currently in use in the following yards:
Piston retarders are used to afford constant speed control throughout a classification yard, and to ensure soft low impact couplings in the classification tracks. (Typical Coupling speed is 1.79 m/s (4.0 mph))
The advantage is that all cars will travel at constant speed between switches, within ± 0.5 mph (± 0.22 m/s) from the set speed.
Classic clasp retarders employ a system of “catch-and-release” and require very high crest gradients and long entry leads to accommodate the installation of clasp retarders.
Piston retarders are easy to install.
Piston retarders are easy to maintain. The piston retarders can be maintained without excessive loss to track operating time. Maintenance can be done between trim operations, or in tracks that are not being used, without disrupting the overall flow of the yard.
Piston retarder parts are small and can easily be stored in stock, and at low cost.
Piston retarders does not require very advanced control software, as is the case with clasp retarders, to control it ’s speed control capabilities. Regular yard switching software is all that is required.
The piston retarders are completely self contained and no external software, hydraulic, or electrical control is required for the piston retarder’s operation.
