They arrived in Ireland in mid 1979 going into service soon afterwards they last ran in revenue earning service in Dec 2009 so about 30 years .
Hope we see a model of them from IRM at some stage .
Allegedly the ESSO wagons being imported from the UK in the early 1970's came complete with overhead wire warning plates thus being the first rolling stock in Ireland to carry them even though we didnt get our first overhead wires until 1981!
Great pictures the First two are ESSO? ( Frist one class A ,second on class B possibly) wagons built by Charles Roberts and brought in Ex UK in 1969/1970.
Great pictures .
I think it was built in the early 1970's to coincide with the arrival of the Mk2D stock from BR and use and maintenance of train sets of them .
