In the early 20th Century arrangement, these were the New York Branch towers in New Jersey:
Ewing West End
Ewing East End
Glenmore West End
Glenmore East End
Hamilton West End
Hamilton East End
Port Reading Junction (a LV operation)
Bound Brook Junction (a CNJ operation)
Double track with center sidings was the big deal; the tower let you in and you let yourself out at the
middle switches unless instructed to run through.
In the teens the line was substantially improved. The functions of Ewing West End were brought in to Trenton
Junction with a table interlocking. Glenmore got a new tower to begin the four-tracked section, along with new
towers at Hopewell, Belle Meade, and Weston. Manville yard was extended to Weston along with the Port Reading
Skillman, perhaps a left-over tower from the prior arrangement, was closed in the 1930's, and Ewing East End
became a remote controlled function of Trenton Junction in 1933.
In the early 1950's the entire line was rationalized with remote control machines at West Trenton (formerly known as
Trenton Junction) and Weston. See: http://rrsignal.com/railroad/towers.htm
The fourth (westward) track was mostly removed and the now center track was made bi-directional. The intermediate
towers were closed and higher speed crossovers installed. A new tower was constructed atop the battery house at
Trenton Junction and the original tower demolished. The remote locations acquired their short names at that
time: Glen, Hope, and Meade.
The three-track arrangement didn't last long; the westward track disappeared in pieces in the late 1950's, but the
bi-directional operation remained on the former center track. Hope was the first to lose its crossovers in the early 1960's.
Port Reading Junction, by now a curious name for the LV crossing, was remoted by the LV in 1955. Bound Brook Junction was
wiped out by a B&O freight train in 1969 and replaced by an operator in a trailer before the CNJ remoted it in the 1970's.
The rest survived until Conrail single-tracked it.
