DPS Electronics’ Dual Function Linkers have changed the game for BRC’s Mechanical employees. 

The linking devices are used to test head end devices (HED) and end of train devices (ETD) prior to departures to ensure they aren’t defective and won’t delay trains. They do so by simulating a distance of 15,000 feet, the range of a fully built train; to function properly, the ETD and HED must successfully communicate at that distance.

Employees began using the linking device in June.

“It’s very efficient; it has enhanced productivity and been a useful tool,” Car Foreman Jason Prosser said.

With ETD/HED tests out of the way, air tests can be performed in blocks as opposed to individually, which results in a more fluid departure experience for crews. It also allows manpower to be deployed more effectively.
