This 4-wheeler diesel locomotive was built in 1953 by the German company Klöckner-Humboldt-Deutz AG (KHD). It was part of a series of 8 engines supplied to various German metre gauge secondary railways. 
Manufactured under builder’s number 55 486, it was fitted with a diesel-hydraulic transmission driving both axles via chains. From the outset, it featured continuous air braking, in addition to a hand brake.
When new, it was assigned to the Herforder-Kreisbahn, near Hannover, under number Köf 14, later V 14.

In 1966 it was transferred to the coastal Sylter Inselbahn, on the island of Sylt (North Sea), where it was re-numbered L14.

In 1971 it was bought by the Juister Inselbahn, another German insular railway, and named “Heinrich II”; it retained number 2 thereafter.

In 1983, it was bought by the Swiss Montreux Oberland Bernois (MOB) railway, which needed motive power for shunting duties. The locomotive, numbered Tm 2/2 n°2, was assigned to Zweisimmen yard. A vacuum braking system was added to the air brakes, and in 1985 the engine was repainted in MOB livery (dark blue with yellow lining).  
Between 1988 and 1990, it was fitted with standard gauge buffers and couplers to haul standard gauge wagons loaded on carrier bogies. This equipment was subsequently removed.

Having become redundant, the engine was sold to the CFBS in 2010. It is used for shunting, and can provide back-up to diesel locomotives 351 & 352 for hauling passenger trains.  
In 2013, the original Deutz diesel motor was replaced by an IVECO motor.
