  • Operating railroad switches
    Patent number: 5772157
    Abstract: The railroad power switch operates from the energy stored in a hydraulic accumulator. A pump charges the accumulator and keeps it charged. A power cylinder acts on the moveable rail of a railroad switch through this hydraulic energy. The energy opens the switch, closes it, and stabilizes it during train trailing through the switch. A spring pack supplements this hydraulic energy in stabilizing the switch.
