The Glasgow & South Western Railway was a modest user of tank locomotives and the 28 of these large ('Class 1) (LMS'3F') were the most numerous. They were designed by Peter Drummond and a later batch were modified with higher water capacity by Robert Whitelegg. 16905 survived (just!) into BR days but never received its BR number.
