SNCB Class 11 is part of the large 1980s family of 144 electric locomotives. The family was made up of Classes 11 (12), 12 (12), 21 (60) and 27 (60). Classes 11, 12 and 21 were nearly twice as powerful as Classes 22, 23 and 25 while Class 27 was more than twice as powerful as these 1950s locomotives. This family was heavily influenced by the Class 20² from the mid-1970s. They were very reliable because of the trial and error development of their predecessor. This family came into service with M4 and M5 coaching stock and the AM 80 and AM 86 series of EMUs. This generation was a major modernization of the SNCB even if the older M2 coaching stock remained active for more than a decade before being replaced. The only real difference between a Class 11 and a Class 21 was the Class 11 had a transformer inside to allow working under both 3000 V DC in Belgium and 1500 V DC plus Dutch signalling and train protection for working in Holland. Externally they were identical to Classes 12 and 21 aside from the livery and a few minor details.

The SNCB Class 11 locomotives were built in the 1980s for hauling the Benelux trains between Brussels, Belgium, and Amsterdam, The Netherlands. They operated in the push pull mode - remotely controlled from a leading driving trailer when at the rear of the train. They are numbered 1181-1192 to avoid clashing with NS Class 1100 locos that were still in use at that time. The Dutch Class 11 was originally numbered from 1101 to 1160. In 2009 they were replaced on the Benelux trains by Bombardier TRAXX locomotives which had been leased from Angel (now Alpha) Trains. When Class 11 locomotives were replaced on international services they were moved to peak hour services within Belgium for the rest of their working lives before retirement. They are painted to match the Nederlandse Spoorwegen (Dutch Railways) coaching stock they used to work with.
