Elizabethport NJ was the hub of the Central of New Jersey repair operations. The original shops are at bottom left, the new shops are at top right. Also shown is the giant Singer Manufacturing plant. (1906 map)

Not the best aerial view of the Elizabethport shops (and Singer), but it's all I have. From a newspaper clipping.

Just to the east, they also had an impressive bridge over Newark Bay. 1958 Elizabeth Quad @ 24,000
