CIÉ Esso Tank Wagon - Quad Pack - Pack 3We are delighted to team up with our Danish friends at Heljan to bring you a run of the former BR Oil tankers bought by CIE in the late 1960s and modified for Irish operations. Synonymous on the "Sligo Oil" trains, these B Class tank wagons were modified with additional bracing between the tank barrel and chassis which we have tooled up to make these authentic for the Irish variants of these distinct wagons.
