One loco, 7005, has been preserved by PFT at Saint Ghislain, the remainder were scrapped after they were displaced by class 77s.cite web |url=http://www.belrail.be/F/fiches/shunter/fiche70.html |title=Locomotives de manoeuvre de la série 70

Built 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 aCockerill diesel engine to replace its original Anglo Belgium Cy unit.cite web |url=http://www.pfttsp.be/index.php?option=com_content&task=view&id=339&Itemid=61&lang=en_GB |title=PFT/TSP - 270.005
