No. 114 built at Horwich with a cylindrical firebox, longer than the original typeFootplate view of cylindrical firebox
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 between 1911 and 1914. Crews referred to them as "Sea Pigs" which implies they were not well liked. [3]
Numbering
A total of 60 locomotives were built, all of which passed to the London, Midland and Scottish Railway (LMS) in 1923. The LMS numbered them 12700-12759 and gave them the power classification 5F. By 1948, British Railways (BR) inherited only one surviving locomotive: LMS No. 12727 (L&YR No. 1433), which was renumbered 52727.[4]
Withdrawal
The first locomotive was withdrawn in 1926 and the last in 1950. None were preserved.
