what is it?

The Heilmann locomotives were a series of three experimental steam–electric locomotives produced in the 1890s for the French Chemins de fer de l'Ouest (CF de l'Ouest). A prototype was built in 1894 and two larger locomotives were built in 1897. These locomotives used electric transmission, much like later-popular diesel–electric locomotives and various other self-powered locomotives.
