Nord 2.121 to 2.180 were a class of 60 four-cylinder 4-4-0 compound steam locomotives of the Chemins de fer du Nord; they were used as express passenger train locomotives. They were placed in service in 1898 and all but four had been retired by 1933. At the creation of the SNCF in 1938, the surviving locomotives were renumbered 2-220.A.1 to 2-220.A.4

History

Two prototypes were designed by Alfred de Glehn, of SACM and Gaston du Bousquet of the Nord as an improvement from the No. 701 built in 1884. They were four-cylinder compound locomotives. One of them initially lacked a coupling rod, making it a 4-2-2-0, but wheelslip issues quickly ended the experiment.^[1] In 1903, locomotives 2.121 to 2.123 and 2.126 were sold to the Compagnie du Nord - Belge who renumbered them 307 to 310.^[2]

Construction

SACM delivered two prototypes from their Belfort factory in 1891, and later delivered all the production locomotives:
