The GWR 3501 Class were ten broad gauge 2-4-0 locomotives built by the Great Western Railway.

Contents

They were built in 1885 as 2-4-0 T locomotives, but five were rebuilt in 1890 as 2-4-0 tender locomotives for working express trains between Exeter and Plymouth. They comprised the first ten locomotives of Lot 64, the remainder of which comprised ten similar locomotive Nos. 3511 to 3520 built to the standard gauge. In 1892 the broad gauge was abandoned and the locomotives were all converted to standard gauge tender locomotives, becoming a part of the 3201 Class.

Locomotives of the Great Western Railway List of railway locomotives used by the Great Western Railway

The first Locomotives of the Great Western Railway (GWR) were specified by Isambard Kingdom Brunel but Daniel Gooch was soon appointed as the railway's Locomotive Superintendent. He designed several different 7 ft 14 in broad gauge types for the growing railway, such as the Firefly and later Iron Duke Class 2-2-2s. In 1864 Gooch was succeeded by Joseph Armstrong who brought his standard gauge experience to the workshops at Swindon. To replace some of the earlier locomotives, he put broad gauge wheels on his standard gauge locomotives and from this time on all locomotives were given numbers, including the broad gauge ones that had previously carried just names.

2-2-2 Locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives, 2-2-2 represents the wheel arrangement of two leading wheels on one axle, two powered driving wheels on one axle, and two trailing wheels on one axle. The wheel arrangement both provided more stability and enabled a larger firebox than the earlier 0-2-2 and 2-2-0 types. This configuration was introduced in 1834 on Robert Stephenson's 'Patentee locomotive' but it was later popularly named Jenny Lind, after the Jenny Lind locomotive which in turn was named after the popular singer. They were also sometimes described as Singles, although this name could be used to describe any kind of locomotive with a single pair of driving wheels.

GWR Ariadne Class

The Great Western Railway (GWR) Ariadne Class and Caliph Class were broad gauge 0-6-0 steam locomotives designed for goods train work by Daniel Gooch and are often referred to as his Standard Goods locomotives.

The Banking Class were five 0-6-0ST Brunel gauge steam locomotives for assisting ("banking") trains up inclines on the Great Western Railway. Designed by Daniel Gooch, they were tank engine versions of his Standard Goods class, and mainly built at Swindon Works.

GWR Iron Duke Class

The Great Western Railway Iron Duke Class 4-2-2 was a class of 7 ft 14 in broad gauge steam locomotives for express passenger train work.

The Great Western Railway Sir Watkin Class were 0-6-0T broad gauge steam locomotives. They were designed for working goods trains through to the underground Metropolitan Railway in London. This class was introduced into service between December 1865 and the last was withdrawn at the end of the GWR broad gauge in May 1892. They were all named after directors and senior officers of the railway.

The Great Western Railway Swindon Class 0-6-0 broad gauge steam locomotives for goods train work. This class was introduced into service between November 1865 and March 1866, and withdrawn between June 1887 and the end of the GWR broad gauge in May 1892. The entire class was sold to the Bristol and Exeter Railway between July 1872 and September 1874, where they were numbered 96-109, but returned to the GWR when that railway was absorbed. The locomotives were then renumbered 2077-2090; their names were not restored.

The Gorgon class were six 4-4-0ST broad gauge locomotives operated on the South Devon Railway, Cornwall Railway and West Cornwall Railway. They were designed for passenger trains on this steep and sharply curved line but were also used on goods trains when required.

South Devon Railway Leopard class

The Leopard class were four 4-4-0STbroad gauge locomotives designed for passenger trains but were also used on goods trains when required. They were built by the Avonside Engine Company for the South Devon Railway, but also operated on its associated railways. Although designed for easy conversion to standard gauge this was never carried out.

South Devon Railway <i>Dido</i> class Class of 8 British broad-gauge 0-6-0ST locomotives

The eight Dido class locomotives were 0-6-0ST broad gauge locomotives operated on the South Devon Railway and Cornwall Railway and associated other adjacent railways. They were designed for goods trains but were also used on passenger trains when required.

The GWR 388 class was a large class of 310 0-6-0 goods locomotives built by the Great Western Railway. They are sometimes referred to as the Armstrong Goods or Armstrong Standard Goods to differentiate from the Gooch Goods and Dean Goods classes, both of which were also large classes of standard goods locomotives.

The 3521 Class were forty tank locomotives designed by William Dean to haul passenger trains on the Great Western Railway. They were introduced as 0-4-2T locomotives in 1887, but were quickly altered to become 0-4-4Ts to improve their running. Following two serious accidents they were further altered from 1899 to run as 4-4-0 tender locomotives, in which form the last was withdrawn in 1934.

GWR 1076 Class

The 1076 Class were 266 double framed 0-6-0T locomotives built by the Great Western Railway between 1870 and 1881; the last one, number 1287, was withdrawn in 1946. They are often referred to as the Buffalo Class following the naming of locomotive 1134.

During the 1880s William Dean constructed a series of experimental locomotives to test various new ideas in locomotive construction for the Great Western Railway.

The GWR 378 Class was a class of 30 standard-gauge 2-2-2 steam locomotives on the Great Western Railway in Britain. They were introduced in 1866, and the class remained intact until 1898. Several were altered to the 0-6-0 wheel arrangement, and the last was withdrawn from service in 1920.

The Daniel Gooch standard gauge locomotives comprise several classes of locomotives designed by Daniel Gooch, Superintendent of Locomotive Engines for the Great Western Railway (GWR) from 1837 to 1864.

GWR 481 Class

The GWR 481 Class was a class of 20 2-4-0 mixed-traffic steam locomotives designed for the Great Western Railway by Joseph Armstrong and built at Swindon Works in 1869. They were similar in size to the 439 Class but differed in appearance, thanks to the flowing lines of their outside frames.

The 3201 or Stella Class was a class of standard gauge 2-4-0 steam locomotive, designed by William Dean and built at Swindon Works for the Great Western Railway in 1884 and 1885.

The GWR 3511 class were standard gauge 2-4-0T locomotives designed by William Dean for the Great Western Railway and built in 1885.

NS 3500 A class of 8 Dutch 4-4-0 locomotives

The NS 3500 was a series of express train steam locomotives of Nederlandse Spoorwegen (NS) and its predecessors Noord-Brabantsch-Deutsche Spoorweg-Maatschappij (NBDS) and Maatschappij tot Exploitatie van Staatsspoorwegen (SS).
