The Cockerill 503, built in 1920, is in service for a long time in the ABR workshop in Manage (B) near Charleroi. In 1968, the steam locomotive is replaced by a diesel locomotive. It was then bought by the collector and scrap merchant “De Lille” in Maldegem and deteriorated in the cold and rain until 1999.
After the locomotives were bought in 1999, it took a lot of patience to find a suitable workshop. In view of its poor condition, the locomotive is repeatedly rejected. Finally, a Slovakian workshop declared itself willing to do the work, at a reasonable price and in a relatively short time. However, a completely new boiler still had to be built. This could be carried out in the Czech Republic, more precisely at ZVU Potez in Hradec Kralove.
Thus, since 2002, visitors have been able to admire it in Fond-de-Gras. As it is quite small and, with its weight of 15 tonnes, also quite lightweight, it can sweep easily (probably a big word for a locomotive?) and therefore regularly takes part in events not only in Luxembourg, but also in Belgium, France and Poland.
