Whilst it is the anniversary this year of the end of steam on BR, in 1968, just 20 years earlier, a series of comparative trials took place across the country, to analyses what was then the best in steam traction design, construction and operation. Not surprisingly, these trials – which took place between April and August 1948, were latched on to by enthusiasts – as a form of competition to see which railway had the best steam types.

‘A4’ Class No. 60004 “William Whitelaw” at York on an enthusiasts’ special in the 1960s. As an express passenger type, it was natural to choose one of Gresley’s A4s, but 60022 “Mallard” did not acquit herself well, and was substituted by 60033/34 for the Interchanges. Photo Courtesy: Lens of Sutton
70 years ago, a series of trials took place on the newly nationalised British railway network, to contrast and compare the best elements of the locomotive engineering design, and practice used by railways across Britain. Well, at least that was the plan.
The trials led, eventually to the new BR Standard steam locomotives, and covered espress passenger, mixed traffic and freight types, including a selection of some of the latest designs, WD ‘Austerity’ types, and some traditional designs. The process was not particularly controversial, but new steam locomotives in the 1950s – especially as diesel and electric traction had already been established, and was developing rapidly.
The LMS built this 2-8-0 in huge numbers – with over 600 in service by 1948. Many having been built by the other main line railway companies, Beyer Peacock and North British Loco. for war service at home and overseas. A natural choice perhaps for the 1948 trials. Photo: RPB Collection
It may be that one of the main drivers was the ease of availability of coal as a fuel,where oil had to be imported, and the cost of electric traction’s infrastructure was expensive in the post-war economy of the UK.
