I'm trying to compile a master list of all CNJ stations, complete with opening and closing dates as well as mileposts (if available). anyone who can post what they know, please share! thanks!
The Official Guide would be the logical source for that, what a great book!
Keep in mind that originally, NY&LB stations were owned by the NY&LB, but were contracted to CNJ contractors to be built, and had the "CNJ look" and were painted in CNJ structure colors. They might not "count" as CNJ stations in the strictest sense, as they sold tickets for CNJ and PRR, but this is your list, so do what you wish.
NY&LB is a railroad that never owned a single rail car or locomotive, nor ever ran a train of its own!
