Norwood & St Lawrence 2-6-0 "Mogul" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 205 (Locobase 12652)

Data from DeGolyer, Volume 25, p. 204. Works number was 21594 in January 1903.

Locobse 11421 notes that the N & St L was a slow-growing railroad that didn't reach the St Lawrence River on the New York border until 1909. This Mogul was originally ordered by the Quakertown & Eastern, but sold to the N&StL before its delivery.

Class 209 (Locobase 14955)

Data from DeGolyer, Volume 65, p. 224. Works number was 53944 in November 1920.

The N&StL preferred Alco products for its new locomotives, but did buy from Baldwin on occasion. This shortline Mogul arrived on the 21-mile (33.8 km) line (18 main, 3 yards and branches) seventeen years after the last one. The purchase came at the time when St Regis Paper gained a controllling interest in the railroad.

Class 211 (Locobase 14959)

Data from DeGolyer, Volume 80, p. 226. Works number was 59608 in October 1926.

Three years after Alco-Cooke's Mogul arrived on the N&StL, Baldwin supplied this engine, which had the same power dimensions. Like the Cooke, the 211 used outside radial valve gear to actuate piston valves. In the 211's case (and likely the 210's), the valves measured a 9 1/2" (241 mm) in diameter.

Steamtown's special history study on the 210 at is a detailed account of the railroad and the Cooke's career. Locobase suspects that the two engines were essentially sisters, but has not been able to confirm that they had the same detailed specifications.

Class unknown (Locobase 11421)

Data from "Locomotive Building," The Railroad Gazette, Vol XLII, No 26 (28 June 1907), p 947

When the N & St L procured this little Mogul, the railroad had managed to build only the 7 1/2 miles of 70-lb track (1/2 mile actually used 56-lb rail) between Norfolk and Raymondville in northern New York. It took a consolidation with the Raymondsville & Waddington on 6 January 1909 for the railroad to reach the St Lawrence River.
