TrainLink Telemetry
Systems Head of Train Devices

The TrainLink Telemetry System consists of an End Of Train (EOT) device and a Head Of Train (HOTD) device. The EOT monitors critical last car information such as brake pipe pressure, motion status, battery condition and marker light status and communicates this information to the HOTD using radio communications. The HOTD displays this information to the locomotive engineer to help operate the train.
Head of Train Device
The HOTD is a telemetry transmitter & receiver that provides the locomotive operator with the ability to monitor and operate the associated End of Train. The HOTD also has the ability to initiate a pneumatic emergency at the back of the train by commanding the EOT to vent brake pipe pressure.
HOTD Options
There are two types of HOTDs. One is a standalone HOTD. It is located on the control stand and has all the displays and controls built into the unit. The other is an integrated HOTD (shown above). It is located in the equipment rack of the locomotive and the locomotive electronic display provides the user interface.
