Newburgh & South Shore 0-10-0 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 99 (Locobase 14382)

Data from DeGolyer, Vol 78, pp. 132+. Works number was 58488 in June 1925.

Short as the seven-mile N&SS was, its traffic levels demanded a strong engine. Five axles laid out in an all-adhesion layout allowed for the required tractive effort.

Through World War II, the 99 transferred freight cars in the Cleveland area. In 1948, the N&SS sold the 99 to scrap dealer Iron and Steel Products of Chicago.
