History

edit

They were broadly similar to the earlier Greater Britain class, the principal difference being smaller driving wheels, as their intended use was on the more-steeply graded Northern Section.

The first of the ten locomotives was built in February 1894, and the remaining nine came from Crewe Works between January and April 1898.

They were three-cylinder compound locomotives: the two outside high-pressure cylinders drove the trailing drivers via Howe-Stephenson valve gear, the one inside low-pressure cylinder drive the leading drivers via a slip eccentric. There was no connection between the two sets of drivers.

All the locomotives were named; one unusual feature (shared with the Greater Britain class) was that the names were split over two nameplates, one on each driving wheel splasher. This necessitated the use of two-word names, rather than some of the abbreviated names the LNWR had previously used. The names chosen continued the Greater Britain theme.

They continued in service until Webb's retirement. His successor, George Whale, preferred simple superheated locomotives; consequently they were all scrapped between 1907 and 1912.
