GWR Joseph Armstrong locomotives (Wolverhampton)

Last updated

Between 1854 when the Shrewsbury and Chester and Shrewsbury and Birmingham Railways were absorbed by the Great Western Railway, and 1864 when he moved south to Swindon Works, Joseph Armstrong occupied the post of the GWR's Locomotive Superintendent, Northern Division, at Wolverhampton Works. For ten years the task of providing new locomotives for the GWR's newly acquired standard gauge lines fell jointly to Armstrong and to his superior Daniel Gooch, the railway's principal Locomotive Superintendent who was based at Paddington.

This article deals with the new locomotives designed by Armstrong during his Wolverhampton years. For his later, Swindon locomotives, see the individual articles as listed in the table of GWR Locomotives at the foot of the article.

The locomotives

At the start of his GWR career (1854-8), Armstrong was concerned principally with keeping the motley collection of S&CR and S&BR locomotives in working order, and with enlarging Wolverhampton (Stafford Road) Works. He eventually began new construction there in 1858/9. These were the four classes of locomotive newly built at Wolverhampton during the Joseph Armstrong years:

The 7, 30 and 110 Classes

These were three differing types of 2-2-2 engine (initially of the Jenny Lind type), though they are recorded as a single class in the GWR diagrams. Nos. 7 and 8 (6 ft 3 in or 1,905 mm driving wheels) were built in 1859, No. 30 (6 ft 6 in or 1,981 mm wheels) in 1860, and the fourth, No. 110 (6 ft 0 in or 1,829 mm wheels), in 1862. [1] These, Armstrong's first new locomotives, already show a strong independence from Gooch's ideas, and reflect Armstrong's work with Thomas Gray at Hull and Brighton. Holcroft discusses a fifth 2-2-2, No.32, [2] but since this was regarded entirely as a renewal of an S&CR locomotive, Tabor does not treat it as part of this series. [3] Nos. 7 and 8 were withdrawn in 1876 and 1883 respectively, but in 1883 and 1887 Nos. 30 and 110 were nominally renewed under George Armstrong as 2-4-0s, officially as members of the 111 class (see below). [4]

The 111 and 3226 Classes

Nos. 111-114 and 1004–5, originally a series of six 2-4-0s with 6' diameter driving wheels built in 1863/4. The class was enlarged by George Armstrong in 1866-7 by the addition of another dozen, Nos. 1006-1011 and 372-377, and in 1886-7 by another two by "renewing" singles Nos. 30 and 110. Finally, after years of building only tank engines, Wolverhampton added another six entirely new locos to the class in 1889, Nos. 3226-3231, bringing the class total to 26. Intended for secondary trains, the original 111s were initially shedded at Chester for trains to Birkenhead, to Manchester, and south to Wolverhampton. Some of the later engines were allocated to Hereford, and the class subsequently worked further south, on the Gloucester and Oxford routes. The older locos were withdrawn between 1903 and 1914, while some of the 3226 series (which worked mainly in the West Midlands) remained in service until 1922. [5]

The 17 Class

Nos. 17, 18, 1002, 1003, 11, 177, 344-346, nine 2-4-0 tank engines built in 1864. [6] Nos. 17 and 18 were numbered 1A and 2A until July 1865; 1002-3, 3A and 4A until Sept. 1866; 227 was 177 until August 1867 and then 238 until July 1870. The class was not uniform but to start with all had back and well tanks, inside frames, and domeless boilers. Soon all were fitted with short saddle tanks instead of the apparently unsatisfactory well tanks. In early days these engines worked from Wellington and Croes Newydd sheds, but later some migrated to south Wales, Swindon, and the London area. They were all withdrawn between 1883 and 1893. [7]

The 302 Class

Nos. 302-309, eight outside-frame 0-6-0 saddle tanks built in 1864-5. [8] These have slotted frames as on the 360 Class tender engines, to which they roughly correspond. They were the first of the larger type of GWR tank locomotive, and had long lives. No. 302 was still a saddle tank when withdrawn in 1918, but the others became pannier tanks when reboilered with Belpaire fireboxes between 1911 and 1923. The last two to be withdrawn were Nos. 303 and 306 in summer 1932, at the age of 68 years. [9]

The Armstrong brothers

Since 1864 was the actual year in which Joseph Armstrong transferred to Swindon, and George took over at Wolverhampton, it does not seem possible to attribute the 17 and 302 classes to either of the brothers with absolute certainty. Holcroft discusses the classes in his chapters on both brothers, [10] while Tabor simply indicates that the relevant engines were built at Wolverhampton, without specifying their designer.

The GWR 1400 Class is a class of steam locomotive designed by the Great Western Railway for branch line passenger work. It was originally classified as the 4800 Class when introduced in 1932, and renumbered in 1946.

Wolverhampton railway works was in the city of Wolverhampton in the county of Staffordshire, England. It was almost due north of the city centre, and is commemorated with a small display of level crossing gates and a plaque. Known as the Stafford Road Works, it was opened by the Shrewsbury and Birmingham Railway in 1849 to maintain bought-in locomotives.

Joseph Armstrong was an English locomotive engineer and the second locomotive superintendent of the Great Western Railway. His younger brother George and one of his sons also became outstanding engineers in the employment of the GWR.

During the 1880s and 1890s, William Dean constructed a series of experimental locomotives to test various new ideas in locomotive construction for the Great Western Railway.

George Armstrong was an English railway engineer. He was in charge of standard gauge steam locomotives for the Great Western Railway at Stafford Road Works, Wolverhampton, from 1864 to 1897. He was the younger brother of his colleague Joseph Armstrong, but thanks to the special requirements of the GWR at a time when it was split in two by the broad and standard gauges, the brothers were able to work largely independently of each other. George is best remembered for his 0-4-2 and 0-6-0 tank engines; these were long-lived, and even when life-expired they were replaced by Collett and Hawksworth with remarkably similar locomotives, the well-known 1400, 5700 and 1600 classes.

The GWR 1901 Class was a class of 120 small 0-6-0ST steam locomotives. Numbered 1901–2020, they were designed by George Armstrong and built at the Wolverhampton railway works, England, of the Great Western Railway between 1881 and 1895. They had wheels of 4 ft 0 in (1.219 m) diameter and a coupled wheelbase of 13 ft 8 in (4.17 m).

<span class="mw-page-title-main">GWR 645 and 1501 Classes</span>

The GWR 645 and 1501 Classes were two closely-related classes of 0-6-0ST designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six, the 645 Class, were constructed between 1872-3, of which three were built for the South Wales Mineral Railway (SWMR), two for the Carmarthen and Cardigan Railway (C&CR) and the remainder for the GWR. In essence, they were saddle tank versions of his GWR 633 Class of 1871. From 1878, a further 72, the 1501 Class, partially enlarged, were added. Unlike the originals, these had full-length saddle tanks from the start.

<span class="mw-page-title-main">GWR 517 Class</span> Class of 156 British 0-4-2T locomotives

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 1884–1885.

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.

<span class="mw-page-title-main">GWR Queen Class</span>

The Queen Class was Joseph Armstrong's last class of 2-2-2 express engine for the Great Western Railway, larger than the Sir Daniel Class of about a decade earlier. They worked express trains for almost 30 years, and were in effect the predecessors of the larger Singles of William Dean.

The 927 Class or Coal Goods was series of 20 0-6-0 freight steam locomotives designed by Joseph Armstrong for the Great Western Railway, and built at Swindon Works in 1874. They were numbered in the series 927–946.

The GWR 439 Class, nicknamed the Bicycle Class because of its unusual appearance, was a series of six 2-4-0 mixed-traffic engines designed by Joseph Armstrong for the Great Western Railway, and built at Swindon Works in 1868. The "Bicycles" worked at Northern Division sheds, running between Wolverhampton and Chester.

<span class="mw-page-title-main">GWR 481 Class</span>

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 806 Class was Joseph Armstrong's last design of 2-4-0 mixed-traffic locomotives for the Great Western Railway, built at Swindon Works in 1873. A further 20 similar locomotives were added by Armstrong's successor William Dean in 1881-2; numbered 2201–2220, these had modern domeless boilers. The class had a similar appearance to the 717 Class but had driving wheels 6 in (152 mm) larger.

The GWR 56 Class were 2-4-0 tender locomotives designed for the Great Western Railway by Joseph Armstrong and built at Swindon Works between 1871 and 1872.

<span class="mw-page-title-main">GWR 455 Class</span>

The GWR 455 Class, also called the "Metropolitan" or "Metro" Tanks, was a series of 140 2-4-0T locomotives built for the Great Western Railway, originally for their London suburban services, including running on the underground section of the Metropolitan Railway, the source of their nickname. Later on the class was seen on many other parts of the GWR system. Sixty "Metro" Tanks were built, from 1868 onwards, during the lifetime of their designer, Joseph Armstrong. His successor William Dean regarded the class so highly that he would add a further 80, the final 20 examples appearing as late as 1899. The "Metros" were all built at Swindon Works, in nine lots of ten or 20 engines each.

<span class="mw-page-title-main">GWR 1016 Class</span>

The 1016 Class consisted of sixty double framed 0-6-0ST locomotives designed by George Armstrong and built at the Wolverhampton Works of the Great Western Railway between 1867 and 1871. Like the earlier 302 Class of Joseph Armstrong, the 1016s had 4 ft 6 in (1.372 m) wheels and a 15 ft 6 in (4.72 m) wheelbase, dimensions that would remain traditional for the larger GWR pannier tanks right through to Charles Collett's 5700 Class, and with little change to Frederick Hawksworth's 9400 Class of 1947.

<span class="mw-page-title-main">GWR River Class</span>

The 69 Class designed by William Dean for the Great Western Railway consisted of eight 2-4-0 tender locomotives, constructed at Swindon Works between 1895 and 1897. Nominally they were renewals of eight 2-2-2 engines that carried the same numbers, these themselves having been renewals by George Armstrong at Wolverhampton of 2-2-2s designed by Daniel Gooch as long ago as 1855.
