RailComm says it has provided New Jersey Transit with a control system for several derail devices as part of the NJT’s ongoing upgrade of Hoboken Rail Yard, a major service and storage facility for the rail corporation.
A RailComm Control Panel is located adjacent to the wheel truing machine pit and controls the derail devices. Operation of each derail is enabled via a keyed selector switch on the derail control panel. Blue and amber LEDs are mounted on the building end walls.
Upon derail activation, the derail is applied on the track and the automatic blue flag is raised. The blue LED illuminates when the derail is applied and the blue flag is on, while the amber LED illuminates when the derail is open and the blue flag is off.
