The L&YR Class 30 was a class of 0-8-0 steam locomotives of the Lancashire and Yorkshire Railway. The class was designed by John Aspinall and introduced in 1900.

Hoy locomotives

No. 114 built at Horwich with a cylindrical firebox, longer than the original type

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The first locomotive was withdrawn in 1926 and the last in 1950.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.
