The LNWR Teutonic class was a class of 10 passenger three-cylinder compound 2-2-2-0 locomotives designed by F. W. Webb for the London and North Western Railway, and manufactured by them in their Crewe Works between 1889 and 1890.

Design

No. 1301 Teutonic in black livery

The design featured a boiler pressed to 175 lbf/in² (1.21 MPa) delivering saturated steam to two outside 14-inch (356 mm) high-pressure cylinders, which exhausted to one 30-inch (762 mm) low-pressure cylinder inside the frames. All three cylinders had a stroke of 24 inches (610 mm); the high-pressure cylinders drove the rear wheels, while the low-pressure drove the leading driving wheels. As the two pairs of driving wheels were not connected, the locomotives were "duplex drive" or "double-singles".

They were a development of Webb's Dreadnought class; they larger driving and leading wheels, and the additions of cylinder tail rods (which were later removed). There were also further modifications to the Joy valve gear, but the seven locomotives built in 1890 had the inside cylinder worked by slip-eccentric valve gear instead from new.^[1]

Of the ten locomotives, nine were named after ships of the White Star Line, the exception was named after a character in a Walter Scott novel, as it was exhibited at the Edinburgh International Exhibition of 1890.

Decline

When George Whale become chief mechanical engineer of the LNWR in 1903, he started a programme of eliminating Webb's over-complicated duplex compound locomotives. Consequently, the class was scrapped between October 1905, and July 1907, having been replaced by Whale's Experiment class.^[1]
