Engineer and Trainee: An engineer trainee takes NJT 412 east into Berkeley Heights under the watchful supervision of the train's engineer. The siding at Berkeley Heights Train Station in former times was a passing siding for trains to meet or turn on. In the 1980s around the time of the Morris & Essex Re-Electrification Project, NJ Transit upgraded the signaling on the Gladstone Branch and in the process went from Absolute Permissive Block (APB) to Centralized Traffic Control (CTC). During this process, it was decided to no longer use this siding for trains to meet with one factor in this decision being that the siding was not as long as other sidings on the branch. In the early 1990s, the switch at the east end of the siding was removed. The end result: the siding is now only used occasionally to store maintenance equipment, as seen here. Also, note that the Arrow III units have their original pantographs here. The Arrow III fleet had their pantographs replaced in the early 2010s.
