Portable Cab unit.

The INTELETRACK TELEMETER is an end-of-train monitor system. The system measures the air-brake pressure or vacuum at the end of the train and transmits the information to the driver in the cab via a radio link. More than 500 Inteletrack telemeter systems are in operation in South- Africa, and several systems are in operation in other countries around the world. The Telemeter system can interface to track-side equipment like low cost dragging equipment detectors, hotbox detectors and point switching equipment. A complete telemeter system consists of a cab unit mounted or stowed in the cab of a train where the crew operates and a rear unit mounted with a clamp on the last wagon of the train.


The cab unit consists of a microprocessor, radio modem and 16 digit alpha-numeric LCD display, with backlighting for night visibility, and an integral antenna. The cab unit receives the messages from the rear unit via a radio-modem. The air-brake pressure or vacuum is displayed on the Cab unit's LCD display. The status of the cab and rear unit’s batteries are also continuously displayed. If the pressure drops below 400 Kpa or the vacuum is less than -35 Kpa, a buzzer will be sounded and a red alarm light will flash. If communication is lost with the rear unit, the cab unit will display an error message "NO COMMUNICATIONS". All alarms are logged in a non-volatile ram buffer. The INTELETRACK Telemeter system is designed to be a simple, rugged and reliable system. Maintenance is done by changing modules. All components are readily available from local suppliers.
