Kolzam works of
Racibórz were founded in 1858, initially as railway repair shop.
In 1973 manufacture of rolling stock repair equipment was initiated, followed
later by vehicles: WM-10 railcars for auxiliary duties and track maintenance
(a few hundred built, including many modifications and special versions) and
several railbuses. In 1998 an attempt to enter motive power manufacturing was
made: design work began on a light two-axle diesel locomotive with hydraulic
transmission, intended as a light switcher and for light freight traffic on
secondary lines. Power was provided by six-cylinder inline diesel engine of
the SW680 family, derived from license-built Leyland units for buses and
trucks. It was rated at 245 hp and power transmission was provided by Clark LMHR 28660 hydraulic torque
converter. Prototype,
type 418D, was completed in late 1999 and sold to Metro Warszawskie (Warsaw Underground) for switching at the main
Kabaty depot. A slight modification turned out to be necessary, as buffer beams
did not match the company’s vehicle gauge (due to power supply from
side-mounted third rail). Second 418D was sold to a food industry plant in
Szamotuły. In 2002 Metro Warszawskie
purchased second example, type 418Da, with minor modifications, including
brake control system and improved air compressor. No more locomotives of this
type were built. Kolzam was
declared insolvent in 2006 and was later taken over by Hungarian Mavex-Rekord Kft. as a subsidiary. Main
