IRDOT-P
(InfraRed Detector Of Trains, Points/Switching)



Automatically Aligns Turnouts!


Our Infra Red Detector Of Trains (IRDOT) emits a beam of invisible infrared light through a small hole drilled between the ties of your model railroad track.

When a locomotive or railcar passes overhead, it reflects this beam through the same hole to IRDOT's detector.

This, in turn, triggers a circuit which turns on a light or energizes a relay.

Use it to indicate when a train has reached the end of a hidden siding, is located in a tunnel, has cleared hidden staging yard switches and more.

IRDOT's circuitry is independent of track power and detects both powered and unpowered rolling stock without modification.

IRDOT-P mounts to underside of track base board.

Emitter/ detector pair installs through hole drilled between ties.

Trains passing overhead reflect the beam and trip the circuit.

Has additional relay to activate solenoid-type switch machines.

Relay contacts provide power to switch machine for 1 second.
