The compaqny was originally called the Northern Electric Ry., incorporated in 1904 and finally opened as far as Dalton in 1907. It reached Factoryville in 1908, Nicholson in 1912, Foster and Brooklyn in 1915, and Montrose in 1916. In the meantime it underwent a couple of reorganizations, emerging asthe Scranton & Binghamton RR Co. in 1910. After yet another reorganization in 1918 it became the Scranton, Montrose & Binghamton RR Co. -- still apparently with grandiose plans. (All along the way, everyone still called it the "Northern Electric.")
The Depression brought cutbacks from Montrose to Nicolson, then to Factoryville. There was an abortive effort to switch to buses, but the PUC gave Frank Martz operating rights on the route, and the interurban ceased operations July 20, 1931.
Thomas F. Flanagan's book "Northern Electric Railway" was published by Ben Rohrbeck Traction Publications in 1980. It's obviously long out of print, but hopefully you can find a copy somewhere.
