The NMBS/SNCB Class 77 (also known as HLD 77 or HLR 77) is a class of 4 axle B'B' road switcher diesel hydraulic locomotive designed for shunting and freight work manufactured at the beginning of the 2000s by Vossloh Schienentechnik/Vossloh Locomotives at the Maschinenbau Kiel plant in Kiel, Germany for the National Railway Company of Belgium (SNCB/NMBS).

Background and design

The initial order for 90 locomotives was given to Siemens in 1997 to replace an aging diesel fleet; the railway opted for a locomotive suitable for both shunting and mainline use, rather than separate classes. [4] Siemens sold its locomotive manufacturer division (Siemens Schienenfahrzeugtechnik) to Vossloh in 1998. [5]

The locomotives were variants of the standard MaK G 1200 series design, [2] and are considered a development of the MaK G 1205 type. [1] The locomotive is an off-centre cab design with a two-speed Voith hydraulic transmission driving all axles via cardan shafts. [2] Auxiliary electrical supply is provided by an engine mounted alternator. [4] Unlike many other MaK locomotives which use a MTU or CAT 12-cylinder V engine the locomotive has an ABC 6-cylinder inline engine. [3]

The first locomotive was delivered in October 1999, and worked satisfactorily; a second order for 80 locomotives was given in June 2001. [4] [6]

Operations

The first locomotive entered service in February 2004. [7] All 170 units were operational by June 2005. [8]

Due to its relatively low power the locomotives work in multiple on heavy freight trains.
