|1911 map of the New Jersey Junction Railroad
Turns out that all the shares belonged to the New York Central and Hudson River Railroad Company (hence the big names involved), but there was certainly already lots of business to be had on the West Shore of the Hudson in 1911, and probably more importantly, the need for the connection between the West Shore RR (also owned by the NYC) in Weehawken to Jersey City and another access point to Manhattan, etc. Along the way the NJJRR ran across the Erie and the DL&W that went to the Hudson as well. The line ran right alongside the Erie's Weehawken Branch line, and I believe became part of Conrail's River Line branch.
