IPD Switch Machines with ECC

The M-3 IPD and M-23A IPD switch machines with ECC consist (essentially) of a motor, gear train, motor controller, and circuit controller with electronic point detection. Each machine type uses the same base casting and is generally interchangeable as to mounting and connections in a switch layout. The M-23A IPD machines are taller than the M-3 IPD machines, which may affect clearance. The M-3 IPD and M-23A IPD machines are normally motor-operated. The M-3 IPD machine has no hand-throw capability, but can be operated manually using a removable hand crank. The M-23A IPD machines have dual-control capability, with hand-throw and selector levers to allow manual operation. This dual control capability of the M-23A IPD machines requires a different gearbox than that used on the M-3 IPD switch machine. The M-23A IPD machines may also be hand operated using a ratchet wrench applied to the friction clutch adjusting nut.
