NMBS-SNCB HLR 7103 was seen stored at the railroadmuseum in Leuven.

In the 1950s NMBS-SNCB ordered 11 heavy shunting locomotives from a consortium of Baume & Marpent (body), ACEC (electrical and mechanical part) and ABC (engine).Six were numbered in the 270 class (after 1971: HLR 70) and were equipped with a diesel-electric transmission.The other five were numbered in the 271 class (after 1971: HLR 71) and were equipped with a diesel-hydraulic transmission.While class 270/HLR 70 locomotives proved very successful and were in service until 2001, class 271/HLR 71 locomotives were very unreliable and were already withdrawn in 1980.

One locomotive of each class is preserved: PFT-TSP bought locomotive 7005 and restored it into its original livery of the 1950s, while locomotive 7103 was preserved by NMBS-SNCB and is stored at the railroadmuseum.
