Steam Locomotives of the Central Railroad of New Jersey (CNJ)[Inhalt]
Central RR of New Jersey classes I-5 and I-6s
United States | 1903 | 10 produced
Locomotive Magazine, July 1907

The ten class I-5 Consolidations were delivered by ALCO-Brooks in 1903. For burning anthracite culm they were given a Wootten firebox with an 82 square foot grate and Camelback design. In the 1920s, all were superheated, with one locomotive keeping the cylinder diameter of 20 inches and the remaining getting 21 inch diameter cylinders. The former were designated I-5s while the rest became I-6s. The tender capacity was increased by a ton by installing boards. The last four members of the class remained in service until 1947.

Central RR of New Jersey class B-7

The B-7 was a class of five 0-6-0 shunters built by ALCO in 1923. For use in the anthracite mining areas, they had a Wootten firebox with a grate area of 70 square feet. Under the new class scheme of 1945 they were designated 6S46. This represented a switcher with six wheels and a pulling power of 46,000 pounds

Number 113 is the only operational steam locomotive of the Central Railroad of New Jersey today. It was used there until 1951 and then by the Reading Anthracite Co. until 1960. It has been refurbished since 1999 and has been used again by the Reading Blue Mountain & Northern Railroad for excursions since 2013.

Central RR of New Jersey classes G-1s to G-4s ( classes P-43, P-47 and P-52)

The Pacifics of the Central Railroad of New Jersey were loosely based on the Reading class G1, so they had a Wootten firebox. The first classes consisted of six G-1s built in 1918 and five G-2s from 1923. Like the later classes, they had been built by Baldwin.

When the CNJ got access to more soft coal, five G-3s were built in 1927. These had a narrower firebox with a width of eight instead of nine feet. Other improvements included a stoker, a mechanic lubricator, a feedwater heater and a larger tender. Five G-4s followed in 1930 which had smaller drivers and a smaller loading gauge for working through the tunnels in eastern Pennsylvania.

In 1945, the CNJ adopted a new class scheme. They now got the prefix P for “Pacific” and a number that denoted the tractive effort in thousands of pounds. So the G-1s and G-2s became the P-43, the G-3s became the P-47 and the G-4s became the P-52. The last ones were retired in 1955.
