Metropolitain 0-6-4 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 032T (Locobase 20145)

Data from [].

These two engines were built by the Nord in anticipation of winning approval for a line that would run from the gare du Nord along the Champ de Mars via les Halles. Unfortunately for the Nord, chances for approval foundered on the distaste for operating steam locomotives underground in the city. Doubtless, even then the authorities had seen accounts of similar rail lines in cities such as London and New York. In all three cities, underground rail would have to wait for the development of electrified lines, which in fact lay not far off in the future.

The two trial horses remained in service on the Petite Ceinture for decades.
