Central RR of New Jersey 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 333 (Locobase 11675)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 14, 154.

Works numbers were 9333, 9335 in July 1888.

These two Consolidation camelbacks were designated I3 in 1903 and operated for more than 2 decades. They were scrapped in March and April 1930


Class 340 / I2a (Locobase 11676)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 14, 154.

Works numbers were 9460-9463, 9467 in September 1888; 10771, 10774-10780, 10784 in April 1890.

These were identical to the Reading camelbacks supplied by Baldwin in the previous year (Locobase 11662). In 1903, they were redesignated I2a and renumbered 328-332, 358-367 (but not in the original order). All of them served into the 1920s. The first was scrapped June 1923 (329) and the last (361) in August 1929.


Class 425 / Ix (Locobase 12199)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 20, p. 135. Workd number was 14814 in April 1896.

Locobase cannot say why the CNJ ordered just one camelback Consolidation from Baldwin during this period. It seems that the railroad build only a couple of dozen and would buy those from Brooks. Instead, the CNJ went for 4-8-0s.

370 (ex-425) went in solitary order to the ferro-knacker in August 1933.


Class I1 (Locobase 11772)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 10, p. 24 . Works numbers were 5010, 5012, 5027, 5030 in March 1880 and 5044-5045, 5056, 5059 in April.

Built before the age of the Camelbacks on the Jersey Central, this octet of Consolidations had some special features picked out in the specs. All of the rivets in the firebox were countersunk by lapping the crownsheet edge down 2" to stiffen the joint. Also, the grate had 8 water bars measuring 2 1/4" in diameter.

This class enjoyed 40-year careers with the CNJ. Half of the class -- 184, 189, 187, and 186 -- were rebuilt as 0-8-0 switchers in 1898 and 1900, but all of them regained their leading trucks by 1904. Scrapping dates ranged from October 1920 to November 1924.


Class I2 (Locobase 11864)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 13, p.191.

Works numbers were 8377, 8380, 8391-8392 in February 1887; 8421-8422, 8430, 8433, 8449, 8452, 8458, 8460 in March; 8477, 8484-8485, 8490, 8494, 8511, 8515 in April; 8927-8930 in December; 9304-9305, 9308, 9310 in June 1888; and 9346 in July.

This large class of camelback Consolidations was identical to those produced in the same period for the Chicago & Indiana Coal Road (Locobase 11841) and the Philadelphia & Reading (Locobase 11784). The class served the CNJ for about 25 years before being scrapped througout the 1920s.
