The British Rail Class 56 Type 5 Co-Co diesel locomotive was first introduced in 1976 to cope with the increased requirement for heavy freight. British Rail awarded the contract to design and build these new engines to Brush Traction in Loughborough, who subsequently sub-contracted the construction to Electroputere in Romania, due to the lack of capacity in their own works.
The initial 30 locomotives to be delivered from Romania suffered from transit damage and construction deficiencies and had to be extensively rebuilt before entering service. With this in mind the decision was made to build the remaining 105 locomotives in England, British Rail Engineering Ltd manufacturing them at their Doncaster Works (nos. 56031 to 56115) and Crewe Works (nos. 56116 to 56135). The design specification was based upon the Class 47 bodyshell, with the omission of redundant features such as the headcode panel.
Power came from a Ruston-Paxman unit that was similar to that fitted in the Class 50 locomotives, which provided the capability for heavy haul freight. Air brakes were fitted for the first time in a British Rail engine and the electrics were improved in a number of areas, resulting in a more robust power unit. Nicknamed as Gridirons or “Grids”, the Class 56 displaced the Class 20 and Class 47 locomotives and commonly undertook the transportation of iron ore, coal, aggregate and steel across the Eastern and London Midland Regions and on the Western Region for aggregate duties.
Strong and reliable performers, the locomotives were popular, but needed heavy maintenance, particularly when compared against the Class 66 locomotives that came to displace them in service. The introduction of the Class 60 locomotives saw a gradual reduction in the use of the Class 56 locomotives and with the arrival of the Class 66 locomotives, with their greater availability and lower maintenance, the Class 56 fleet were placed into storage between 1998 and 2004.
The majority of the locomotives remain in depots around the UK, despite being variously sold for scrap and then re-acquired and reinstated in service. Colas Railfreight operate a small fleet on a rotating basis and British American Railway Services and UK Rail Leasing have a number available for working. Five locomotives, 56006, 56097, 56098, 56301 and 56302 have been preserved.
Locomotive 56018 was built by Electroputere in August 1977 and operated by EWS before being moved to storage in 2004 with a defective turbocharger. Subsequently sold to locomotive provider Europhoenix in December 2011 for export to Hungary, the locomotive ended up on hire for a couple of years to Fertis, for use on the construction of high speed lines in France, before returning to the UK for another period of storage. Re-registered in August 2013, 56018 is now owned by UK Rail Leasing and is based near Leicester.
