The BR Standard steam locomotives were an effort to standardise locomotives from the motley collection of older pre-grouping locos. Construction started in 1951. Due to the controversial British Railways' modernisation plan of 1955, where steam traction was abandoned in
favour of diesel and electric traction, many of the locomotives' working lives were very short: between 7 and 17 years. Many have been preserved, mainly due to being sent to Barry Scrapyard.
