The GWR 1400 Class is a class of steam locomotive

The 517 Class were small 0-4-2T tank engines designed by George Armstrong for local passenger work on the Great Western Railway. They were built at Wolverhampton Works and were outshopped between 1868 and 1885. They were built in thirteen lots commencing with 517–528 and ending with 1477–1488 in...

Precursors

Like the 48xx/14xx, the 517 Class was a lightweight loco for branchline work; it was built at Wolverhampton Works

 between 1868 and 1885.

In this period evolutionary changes included:
  • 517-570 – with 13' 7" wheelbase, inside bearings to trailing wheels, and saddle tanks built 1868-1869.

  • 571-576 – with 13' 7" wheelbase, outside bearings and side tanks built 1869-1870

  • 826-836, 838-849, 1154–1165, 202-05, 215-222, 1421–1432, 1433–1444, 1465-1482 – all with 15' wheelbase with side tanks built 1873-1883

  • 1483-1488 – with 15' 6" wheelbase and side tanks built 1884-1885


Later gradual changes included: Belpaire firebox

, and in this configuration were the direct ancestors of the 48xx class.

In this form, the updated 517's were but a small step away from the 48xx. The wheelbase was still 15' 6", the boiler still rated at only 165 psi, and the wheels 5' 2" and 3' 8". New was the Collett-style cab and bunker and the boiler nominally to a new design. A three bar crosshead was added to the motion. This was a 1924 innovation introduced with the GWR 5600 Class

Two hundred locomotives were built and remained in service until withdrawn by British Railways between...

The Great Western Railway 5800 Class was a twenty-strong class of 0-4-2T side tank steam locomotive. These were introduced in 1933 for light branch work.

. In later life, lack of auto gear was the cause of earlier scrapping of the newer locos as there was no work for them. They were all gone by 1959.

The auto-fitted locos fared little better; scrapping commenced in 1956 and all were withdrawn by early 1965. By the early 1960s several had been 'in store' (parked in an out-of-the-way siding with a tarpaulin over the chimney) for some time, being occasionally steamed to replace failed diesels.

Preservation

Four examples have been preserved, all late withdrawals from service in the 1963-1965 period. All went direct to preservation from British Railways in relatively good condition. The current location of the preserved examples is as follows:
