Twenty of the class, built in 1903, were fitted with Henry Hoy's corrugated cylindrical steel firebox. This was not a great success (the internal flue deformed under steam pressure and water circulation was poor)[2] and they were later rebuilt with conventional boilers.

Numbering

A total of 60 locomotives was built and these passed to the London, Midland and Scottish Railway (LMS) in 1923. The LMS numbered them 12700-12759 and gave them the power classification 5F. In 1948, British Railways (BR) inherited only 1 surviving locomotive. This was LMS 12727 (L&YR 1433 ) and BR numbered it 52727.[3]

Withdrawal

The first locomotive was withdrawn in 1926 and the last in 1950. None were preserved.

gollark: They CAN, yes.
gollark: I don't think OC can do *much* that CC+Plethora can't. Except drones.
gollark: With Plethora, all of those.
gollark: Yes. Mostly.
