The London and North Western Railway (LNWR) Prince of Wales Tank Class was a Pacific tank engine version of the Prince of Wales Class 4-6-0 steam locomotive.

History

Bowen-Cooke's predecessor George Whale had built 50 related Precursor Tank Class 4-4-2 engines. In terms of familial relationships, Prince of Wales Tank was both a superheated and extended version of the Precursor Tank, and a version of the Prince of Wales Class 4-6-0 steam locomotive with side tanks and a bunker which necessitated an extension to the frames and trailing pony truck. They were used on suburban services out of Euston station and from an early date also used on passenger services between Shrewsbury and Swansea (Victoria) over the steeply-graded Central Wales line, a journey of some 120 miles.

The LNWR built 47 of the superheated tanks between 1910 and 1916 under Charles Bowen-Cooke.

LMS service

All passed onto LMS ownership on the 1923 grouping. The LMS renumbered them 6950–6996 and gave them the power classification 4P. Withdrawals started in 1935, their replacements being Class 4 2-6-4T designs by Fowler and Stanier. All were gone by 1941, and no examples were preserved.

The London and North Western Railway (LNWR) Webb Coal Tank is a class of 0-6-2T steam locomotive. They were called "Coal Tanks" because they were a side tank version of Webb's standard LNWR 17in Coal Engine, an 0-6-0 tender engine for slow freight trains.

The Lancashire and Yorkshire Railway Class 5 were 2-4-2T steam locomotives designed by Chief Mechanical Engineer (CME) John Aspinall and introduced from 1889 for local passenger work. Later batches included progressive modifications such as extended coal bunkers and Belpaire fireboxes. The final batch built from 1911 to 1914 under George Hughes incorporating superheated boilers gave increased tractive effort, others were also rebuilt to this standard. When Hughes introduced his classification system in 1919, the more powerful superheated locomotives were designated Class 6. The final examples were withdrawn in 1961.

They were essentially an extended version of the 1185 Class 0-8-2T with a longer bunker, and were also related to the 0-8-0 freight engines. Their main area of work was to be in South Wales.

Throughout its existence the London and North Western Railway re-used the numbers and names of withdrawn locomotives on new ones as they came out of Crewe Works. This resulted in each class of locomotives being allotted numbers virtually at random, with names that adhered to no discernible theme. By 1911 new locomotives were being produced at a much faster rate than old ones were being scrapped, and it became necessary to introduce a new set of names for Bowen Cooke’s 4-6-0 express engines which were beginning to enter service.
