The Great Western Railway (GWR) 1500 Class is a class of 0-6-0 pannier tank steam locomotive. Despite being a GWR Hawksworth design, all ten (nos 1500–1509) were completed under the administration of the Western Region of British Railways in 1949, just after Nationalisation.

The GWR 0-6-0PT (pannier tank), is a type of steam locomotive built by the British Great Western Railway with the water tanks carried on both sides of the boiler, in the manner of panniers. They were used for local, suburban and branch line passenger and goods traffic, for shunting duties, and as banker engines on inclines.

As noted above, 1501 is a member of the GWR Great Western Railway 1500 class, also referred to as the 15xx Class. 108 0-6-0ST tank engines of the 645 Class were built at the GWR Great Western Railway ’s Wolverhampton works between 1872 and 1881. The last 72 of these featured a revised design; the first of which was numbered 1501.

The 1500 class did not appear until after nationalisation and was a short wheelbase heavy shunting design. The 10 locomotives built were different from all other tank designs on the GWR. Above the running plate level they were similar to the 9400 class but the 1500 class had no running plate and had outside cylinders with Walschaert valve gear ...

The design was a major departure from the GWR’s tried and tested pannier tank formula. Designed by Frederick Hawksworth and his team, the 15XX featured a very short wheelbase for negotiating tight curves, as well as outside cylinders and Walschaerts valve gear.

Running numbers: 1500 - 1509. Built: 1949 to lot number 373.. The '1500' class of heavy shunter was an unusual design for the Great Western as it was fitted with outside cylinders, Walschaerts valve gear and no running platform. In addition, most of the separate parts were welded instead of riveted together.

The Great Western Railway (GWR) 1500 Class is a class of 0-6-0 pannier tank steam locomotive but was actually built by the Western Region of British Railways in 1949 at Swindon. 1501 did empty stock workings at London Paddington station but was withdrawn in 1961 and sold to the National Coal Board for use at Coventry Colliery.

2015年2月1日 · The Great Western Railway (GWR) 1500 Class is a class of 0-6-0 pannier tank steam locomotive. Despite being a GWR design, all ten (nos 1500–1509) were built by the Western Region of British Railways in 1949. Coming from a railway company with a well-developed standardisation policy, the 15xx was a strange design finale.

Despite being a GWR design unusually with Walschaerts valve gear, all ten (nos 1500–1509) were built by the Western Region of British Railways in 1949. Above footplate level they were very similar to the GW 9400 class using the same no.10 boiler but below the footplate resembled the USATC S100 ...

2021年11月21日 · GWR practice was to use walschaerts gear on (their few) outside valve gear locomotives - notably the railmotors and the VOR 2-6-2Ts. By this time external steam pipes were standard on GWR outside cylinder classes. The S100, with its very short (10ft) wheelbase drives to and has the eccentric on the rearmost driving wheel.
