railroadclass= 4MT|The GWR 6100 Class is a class of prairie tank locomotives, designed by
Charles Collett , and of the2-6-2 T arrangement.They were introduced in
1931 and were a straightforward development of the earlier 5101 Class (and for that matter the 1905GWR 3100 Class ) with little more than an increased boiler pressure of 225 psi to distinguish them from their ancestors.There were seventy in the class, built in two batches in 1931-1933 and 1935. They were frequently referred to by
trainspotter s as 'Tanner One-ers'- being a reference to their '61xx' numbering sequence using colloquial terms for a sixpence and a penny.ervice
They were specifically built for commuter services in the London area where they replaced the ageing
GWR 2221 Class on these services. They lasted to the end of steam on theWestern Region of British Railways in 1965, never straying far from their home turf. Typical duties were Paddington to Aylesbury via High Wycombe, and from the same terminus to Oxford, Windsor, Reading and Basingstoke. They were mainly shedded at Old Oak Common, Southall, Slough, Reading and Aylesbury throughout their lives. In the early 1960's, the advent of the first generationdiesel multiple units made them semi-redundant though generally far from worn out. Their last few years saw them on more menial duties as in the photograph (top right) until scrapping.Preservation
