Three were initially ordered as prototypes of diesel-electric traction. Three diesel-hydraulic Class 271 locomotives were also ordered for comparison. One loco, 7005, has been preserved by PFT at Saint Ghislain, the remainder were scrapped after they were displaced by class 77s.[1] HistoryBuilt by Belgian locomotive manufacturers Baume & Marpent, the 6 class 270 locomotives were initially allocated to Ronet depot in Namur. Their electric transmission was produced by ACEC under license from Westinghouse. During 1992 7004 acquired a Cockerill diesel engine to replace its original Anglo Belgium Cy unit.[2] After Ronet, during 1961 they were moved on to Antwerpen to perform trip workings to and from places such as Boom, Mechelen, Mol and Turnhout.[3] When, at the start of 1971, NMBS/SNCB adopted their current numbering system they became Class 70.
