SNCF 0-10-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 050 TQ (Locobase 15599)

Data from "050 TQ" from Wikipedia at [link], last accessed 14 November 2013.

The SNCF bought the first twelve engines in 1948 to supplement the 0-10-0 heritage fleet that had come from several sources. They had Kylchap exhausts and used many components that were fitted to a variety of other locomotives. Over the course of their careers, the railway reinforced the frame and increased bunker capacity.

According to Wikipedia, their delivery tripped a series of redistributions. All of the TQs were delivered in 1948-1949 to several depots beginning with Creil and La Plaine followed by Somain, Fives, Lens, and Aulnoye. In 1958, the engines were redistributed to Bourget, Joncherolles, Laon, Compiegne, Boulogne, Calais, Longueau and even Persan-Beaumont in the Parisian suburbs.

The TQs served former Nord stations until 1970.
