London & North Western 2-8-0 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class E (Locobase 2190)

26 four-cylinder Webb Class B compounds rebuilt by George Whale with a Bissel leading truck to become the first Consolidations on the London & North Western. Chris Northedge, author of [] (10 May 2003 -- the website of the London & North Western Railway Society's Goods Locomotives "exhibit" says the conversion reduced the weight on the front end, improved the look and the ride.

Note: Tuplin (1963) gives a nominal tractive effort of 29,000 lb, commenting that it is "that of the simple engine produced by removing the high-pressure cylinders." The number given in the specifications is based on a 1924 ARA formula.


Class F (Locobase 2194)

George Whale rebuilt this batch of 11 four-cylinder Webb compounds as Consolidations like the E class, but with larger boilers and grates. Chris Northedge, author of [] (10 May 2003 -- the website of the London & North Western Railway Society's Goods Locomotives "exhibit" credits the rebuilds with 15" HP cylinders, describing the result as "a powerful, flexible and economic design."

Like the Es, these were later rebuilt as 0-8-0s by Bowen-Cooke.

Note: Tuplin (1963) gives a nominal tractive effort of 29,000 lb, commenting that it is "that of the simple engine produced by removing the high-pressure cylinders." The number given in the specifications is based on a 1924 ARA formula.
