This diesel-mechanical locomotive was built in 1948 by the VFIL* workshops at Lumbres (Pas de Calais) for the VFIL lines of the Pas de Calais (Anvin – Calais and Berck-Aire sur la Lys). According to builder’s data, the engine can haul a 115 metric ton train at 14kph on a 15mm/m gradient. 

In 1956, this diesel was sold to the Régie Départementale des Transports des Ardennes (RDT Ardennes).

When this latter system closed, in 1960, N° 301 was sold on to the SE Somme network where it was immediately pressed into service, putting an end to the use of steam locomotives on the “Sea Bathers’ Railway”.
Upon arrival on the Somme system, the engine was re-numbered "353", to follow on logically from the two “twin” diesel locomotives already in service (N° 351 and 352). Like its fellow diesel engines, it hauled freight trains all the year round, as well as sugar beet trains during the harvest season. But it could also be put in charge of passenger trains during the busy summer months. 
N° 310 broke down in 1970. Two years later, the newly-created CFBS took it over with the remainder of the railway. Having got back its original 301 number, the engine was repaired by volunteers and returned to service in 1979. Over the following 5 years, it hauled tourist trains and special group charter trains on the railway. It was also in charge of work trains and shunting duties... alternating with the other diesel locomotives.
Since the spring of 1984, N° 301 has been out of order and is in storage at Saint Valery Canal works. The original diesel motor needs significant repairs and the wheel tyres are worn out. The engine requires a complete overhaul, which will also imply the fitting of continuous braking. A big job for the future!
