The London Midland and Scottish Railway (LMS) Jubilee Class is a class of steam locomotive designed for mainline passenger work. 191 locomotives were built between 1934 and 1936. They were built concurrently with the LMS Stanier Class 5 4-6-0.

History

The last 5 Patriots of Henry Fowler's Patriot class on order, 5552 to 5557, were built with William Stanier’s taper boiler and so became the first of the Jubilee class. 113 locomotives were ordered straight from the drawing board. They were initially a disappointment; their moderate degree of superheating often left them short of steam. Changes to the blastpipe and chimney dimensions helped to transform them.

On 29 April 1935 no. 5552, the first of the class, permanently swapped identities with no. 5642 which had been named Silver Jubilee on 19 April 1935. This change thus giving the name to the rest of the class, see LMS Jubilee Class 5552 Silver Jubilee.

They are often associated with the Midland Division, i.e. the lines inherited from the former Midland Railway. This is because until the late 1950s, it was rare for any 7P locomotives to work south of Leeds. Until then, Jubilees were the largest express engine normally found on the lines running out of St Pancrasmarker or radiating from Derbymarker. They could nevertheless be found on main lines throughout the former LMS system.

Construction

Although built over only a 3 year period the class had many variations due to improvements being made as they were built. The major differences were:
  • Boilers – 10 variations, mainly affecting the number of tubes. The earlier boilers were domeless but later boilers were domed. There were 2 sizes of fire grate area depending on whether the firebox throatplate was straight or sloping.
  • Bogies – Approximately 50 of the earlier locomotives were built with ex-Claughton bogies which had a 6’3” wheelbase compared to the later locomotives built with new bogies that had a wheelbase of 6’ 6”.
  • Smokebox Saddle – The first 113 locomotives were built with a 2 piece saddle, the rest had a conventional 1 piece saddle.
  • Tenders – 3 basic patterns were fitted; Fowler 3,500 gall. Fowler high-sided (10 off) and Stanier 4,000 gall. However, taking into account rivets, wheelbase, and welds this can be subdivided into a total of 8 patterns.


Withdrawal

45637 Windward Islands was scrapped in 1952 due to damage sustained in the Harrow and Wealdstone rail crashmarker. The remaining locomotives were withdrawn between 1961 and 1967.

Preservation

Four jubilees have been preserved, 5593 Kolhapur, 5596 Bahamas and 5690 Leander have been worked in preservation.

The fourth, 5699 Galatea, was saved from Woodham Brothers scrapyard as a rusting hulk and is slowly being restored. She requires one new set of driving wheels after one of hers was cut up in Barry when she was derailed.
