Ownership changes

In 1923, they all passed to the London, Midland and Scottish Railway, and were classified 3F, and renumbered 17650–17692. On nationalisation in 1948, the twenty-three survivors passed into British Railways stock, and were renumbered by adding 40000 to their LMS numbers.

Note 1

Not all the BR numbers were actually applied because some engines had been withdrawn before 1948. They were withdrawn between 1934–1963, and all were scrapped.

gollark: Using a Lisp-like language for this for no good reason?
gollark: Or something like that anyway.
gollark: Which I think is 128.
gollark: Basically, an analog input with voltage, say, 1.5V when the maximum is 3V, would be encoded as (1.5/3)*256, if you're using 8-bit linear pulse code modulation.
