Barclays built relatively small numbers of narrow gauge locos, and even fewer narrow gauge diesels.
This led to a batch of seven fairly unsophisticated 2’6” gauge diesels – works numbers 554 to 557 and 560 to 562 – being built for the ICI Nobel’s Explosives works at Ardeer, Scotland.
It says a lot for the basic robustness of Barclay’s design that the locos survived the onslaught of peat works life – in the case of number 556, basically unchanged from when it rolled out from Kilmarnock.
