| Built in 1912 and named after the county in which it is located, UNION Tower is unique in that it is a massive four story structure (two stories are below track grade), and was built with a US&S F13 interlocking machine, rather than the more common Model 14. The interlocking machine contained 47 levers, all of which were active, and was electric rather than electro-pneumatic. UNION controlled an extremely elaborate flyover junction of the PRR's Main Line and the NY&LB's (New York & Long Branch) North Jersey Coast Line. The tower was closed in 2011 and all of its duties transfered to Amtrak dispatch. |
