Description
The 4-4-0 wheel arrangement was common in the early days of steam but grew ever more uncommon as the 20th century progressed. Yet the LNER and SR both built new 4-4-0s during the early 1930s with modern practices in mind such as external valve gear. The LMS did however not build any new 4-4-0s with a modern layout at this time, so I decided to make a speculative engine depicting what I think a Stanier 4-4-0 would have looked like. Don’t take any of this as gospel or nothing, this is just meant as a bit of fun with what-ifs

Lore
The Class 2 4-4-0 was a design of light passenger engine meant to replace Victorian machines such as the MR 483 Class with modern, more user friendly designs. They were purposefully designed to be as light as possible as they weren’t meant to haul heavy trains meaning they had a wide route availability. Although the engines proved mechanically successful only 15 would ever be built as it proved more economical to just continue running the old engines over replacing them with newer more efficient designs. All of the engines were originally mated with all-welded Fowler 3.500 gallon tenders with some later on having their tenders changed out for the Ivatt 3.000 gallon tenders. They would rattle on in service mainly as suburban, branch line, or secondary line passenger engines where they usually were seen with one too four coaches in tow.

All class members were inherited by British Railways which reclassified the engines as class 2 mixed traffic engines. A few of the class were transferred to Western region mainly to work over the Cambrian Line as they were light enough to cross the Barmouth Bridge. Among these engines were 40065 which in 1949 revived a major overhaul, this was when it was painted in the BR Green livery as pictured above. 40065 was one of the last members of the class to be withdrawn in early 1962, it was sold for scrap to the Woodham Brothers Ltd. The engine was eventually bought in 1971 by the 40065 Society, it steam once more in August of 1983 after a long and arduous restoration which saw the engine almost being sold back to the Woodham Brothers.
