Class King George (Locobase 20043)
Data from "Narrow Gauge Quarry Locomotive for Achill Island", Locomotive Magazine, Volume 18 (15 June 1912), p. 116. Works number was 1945 in October 1911.
Achilll Island lies just off the mainland of northwest Ireland in County Mayo. A two-foot-gauge steam railway was laid by the IIMC on the island to carry the amethystine quartz (known as Achill Stone) from two quarries. According to Ireland's railwayhostel.ie website entry on Achill , the principal line transported "whitestone from a quarry in Slievemore to Purteen harbour. The second line was from a quarry in Dereens. This line ran six wagons and ended at the pier at Darby's Point, Cloughmore. In 1920 the Keel and Kildavnet industrial lines were closed." (from [

Bagnall's little engine's most notable feature was its circular steel firebox, that was, said LM, "particularly easy to wash out, there being no stays or cramped water spaces ...It has given every satisfaction in working, being a very easy steamer."
