Morbihan 0-6-0 Locomotives in France

Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 6227)

Data from [] (10 July 2004).

The Loire Inferieure metric-gauge network included lines from Herbignac-Guerande, Pornic-Paimboeuf, and Saint Nazaire to La Roche-Bernardhe. These stout six-coupleds carried on until the lines closed, at which point 101 & 103 were sold off to industrial railways.

When the Chemin de Fer Baie Somme tourist line association bought 101, says the CFBS site, the machine went into immediate service at the head of the season's first train. When the Corpet 2-6-0T came on the scene in 1992, 101, which was beginning to show signs of wear, saw more limited service. Although it needed a new boiler and cylinders, other demands took precedence and as of 2004, 101 still awaited reconditioning. It wasn't until 2009 that actual reconstruction began.
