Data from "Heavy Eight-Wheeler for the New Jersey & New York Road," Railway and Locomotive Engineering, Volume 8 (June 1895), p. 341. Works number was 5038 in June 1895.
Originally the Hackensack & New York when chartered in 1856, the New Jersey & New York ran from Rutherford, NJ up through Hackensack (Bergen County's county seat) and the Pascack Valley across the New York state border to Spring Valley and Haverstraw. (commuters in Locobase's home town used this rail line.).
A relatively robust American type and the newest locomotive on the NJ&NY when the Erie took it over, the Park Ridge shed its name but kept its number when it joined the Erie roster. Placed in the miscellaneous D odd class, the 12 remained on the roster until scrapped in 1921.
