Chemins de fer de l'Herault 0-10-0 Locomotives in France

Class Details by Steve Llanso of Sweat House Media

Class H (Locobase 9165)

Wikipedia [] (accessed 2 February 2008).

The Reseau d'Interet Local CF de l'HTrault was a network of secondary lines along the Gulf of Lyon in Southeast France. Sampite provides a summary of all the locomotives then in service on any of the lines and Wikipedia fills in the blanks. Note that none of the series of locomotives (Locobase 9159-9164) had either boiler pressure or grate area. The boiler pressure is an estimate.

These were the biggest steam locomotives to serve the Reseau and served as pushers on several lines.

H-501 amassed 477 073 km (296,262 miles) in 44 years of service.

H-502 totalled 464,938 km (288,726 miles) over that same period.

H-503's career was shorter and the locomotive accumulated only 266,909 km (165,241 miles).
