Green Switch Innovations
Innovation in railroad signal systems





















The MPH-2 consists of a generic panel installed in a water and shock resistant case. Each MPH-2 is capable of disabling 2 tracks, with separate keyed connectors for each track. This allows disabling both units in a back-to-back unidirectional locations or 2 tracks at a bi-directional crossing location.

Features include:

  • A lockout cover plate requires all switches
    to be placed in the "Off" position during
    transport to prevent false setup before
    work begins.
  • Simplified setup and restoration of crossing
    warning systems.
  • Quick disconnect, keyed bayonet-style
  • Heavy duty, military spec components.
  • 12v output provided when MPH's are active,
    can be used for external strobe indication or
    indication to control office using railroad provided
    event recorder.
  • LED indication on the panel when a track is disabled.
  • All circuits are open when the MPH's are not connected
    to the interface harness.




Interface Harnesses are permanently wired in the
crossing house. Individual cables are wired to each
track providing separation for disabling functions.
Cables are labeled for each track and are wired
to reduce the possibility of disabling the wrong track.

20' of cable is provided to enable wiring in any size house.



If a Custom Fixed Panel is preferred.
