The GNSR Classes X and Y were two similar classes of 0-4-2 T steam locomotives built by Manning Wardle for the Great North of Scotland Railway. The two classes were similar, and were used throughout their lives to shunt on the docks at Aberdeen. They passed to the London and North Eastern Railway at the 1923 grouping, and received the LNER classification Z5. The Class X were later reclassified Z4.

History

When the Aberdeen Harbour Commissioners finally agreed to allow steam locomotives to replace horses on the Aberdeen docks, the GNSR purchased two 0-4-2 T locomotives from Manning Wardle for the purpose. These were designated Class Y and numbered 114 and 115. On delivery these were found to be 2 tons over the maximum weight for operating on the docks, [1] and a further two locomotives of similar design were acquired. These Class X locomotives, numbered 116 and 117, had smaller driving wheels and a shorter wheelbase. In order to reduce the weight of the Class Y locos, they initially operated with their tanks only partially filled. [2]

Both classes remained almost unchanged throughout their working lives which involved working the 1.75-mile (2.82 km) long branch from Kittybrewster to Waterloo Docks in Aberdeen, local trips, and hire to nearby industry. They remained in the GNSR livery of black with red and yellow lining until painted unlined black during World War II, although they gained the letters LNER and subsequently acquired BR emblems. The locos also retained their original boilers, there being no spares. Except when on hire to industrial concerns, the locomotives were shedded at Kittybrewster. [3]

The first loco to be withdrawn was 68193 in 1956, followed by 68191 in 1959. The remaining two locos were withdrawn in 1960.

Classification and numbering

After the grouping both the Class X and Class Y became LNER Class Z5. This was changed in 1927 when the Class X was redesignated LNER Class Z4. [2]

London and North Eastern Railway's (LNER) Peppercorn Class A1 is a class of 4-6-2 "Pacific" steam locomotives built between 1948 and 1949 at Doncaster and Darlington Works to a design of Arthur Peppercorn. Forty-nine were built for hauling express passenger services on the East Coast Main Line owned by LNER's successor, British Railways' North Eastern Region. None of the original 49 Peppercorn A1s survived into preservation, with the last being scrapped in 1966. The 50th Peppercorn A1, 60163 Tornado, was completed in 2008 as an evolved member of its class.

<span class="mw-page-title-main">NBR C Class</span>

The NBR C Class is a class of 0-6-0 steam locomotives designed by Matthew Holmes for freight work on the North British Railway (NBR). They were introduced in 1888 with inside cylinders and Stephenson valve gear. A total of 168 locomotives was built, of which 123 came into British Railways ownership at nationalisation in 1948. This was the last class of steam engine in service in Scotland.

<span class="mw-page-title-main">GER Class L77</span>

The GER Class L77, LNER Class N7, is a class of 0-6-2T steam locomotives. They were designed by Alfred John Hill of the Great Eastern Railway and introduced in 1915. The design was perpetuated by Nigel Gresley of the LNER after the 1923 grouping. 134 were built and one example is preserved.

<span class="mw-page-title-main">LNER Class U1</span>

The London and North Eastern Railway Class U1 was a solitary 2-8-0+0-8-2 Garratt locomotive designed for banking coal trains over the Worsborough Bank, a steeply graded line in South Yorkshire and part of the Woodhead Route. It was both the longest and the most powerful steam locomotive ever to run in Britain. It was built in 1925 with the motion at each end being based on an existing 2-8-0 design. The original number was 2395, and it was renumbered 9999 in March 1946, and then 69999 after nationalisation in 1948, although it retained its cab-side plate bearing its original number throughout its life. The locomotive ran for some time as an oil burner, and was tried out on the Lickey Incline in 1949–1950 and again, after the electrification of its home line, in 1955. These trials were unsuccessful, and so the locomotive was withdrawn in 1955 and scrapped.

The London and North Eastern Railway (LNER) D40 class is a type of 4-4-0 steam locomotive inherited from the Great North of Scotland Railway (GNSR). It consisted of GNSR class V and GNSR class F. The two classes were similar but the class F was superheated.

The LNER Class Y10 was a class of two 0-4-0T geared steam locomotives built by Sentinel Waggon Works for the London and North Eastern Railway and introduced in 1930. The LNER numbered them 8403 and 8404 but they were later re-numbered 8186 and 8187. This was the second use of the classification Y10 by the LNER. The first was for an ex-North British Railway 0-4-0 steam tender locomotive, withdrawn 1925.

<span class="mw-page-title-main">NER Class Y</span>

The North Eastern Railway (NER) Class Y 4-6-2T tank locomotives were designed whilst Wilson Worsdell was Chief Mechanical Engineer, but none were built until 1910 by which time Vincent Raven had taken over.

<span class="mw-page-title-main">NER Class X</span>

The NER Class X was a class of 4-8-0T tank locomotive designed by Wilson Worsdell for the North Eastern Railway. They were intended for use as powerful shunting engines to arrange and move coal wagons for loading into ships. In total 15 were built, 10 by the NER between 1909 and 1910, and a further five in 1925 by the London and North Eastern Railway (LNER). They had three cylinders with divided drive: the inside cylinder driving the leading axle, the outside cylinders driving the centre.

The North Eastern Railway (NER) Class K classified as Class Y8 by the London and North Eastern Railway (LNER) is a class of 0-4-0T steam locomotives designed for shunting. It was designed by Thomas W. Worsdell and five of these tiny engines were built in 1890. These were numbered 559-63.

<span class="mw-page-title-main">GER Class G69</span>

The GER Class G69 was a class of twenty 2-4-2T steam locomotives built by for the Great Eastern Railway by S. D. Holden in 1911–12 following the design of two rebuilt examples of the GER Class M15 designed by James Holden, his father, in 1904. They all passed to the London and North Eastern Railway at the 1923 grouping and received the classification F6.

<span class="mw-page-title-main">GER Class M15</span>

The GER Class M15 was a class of 160 2-4-2T steam locomotives designed by Thomas William Worsdell and built for the Great Eastern Railway between 1884 and 1909. The original (F4) class of locomotives were fitted with Joy valve gear which was notoriously difficult to 'set'. This earned them the nickname of 'Gobblers' thanks to their high coal consumption rates. As a result, between 1911 and 1920, 32 of them were rebuilt by James Holden with Stephenson valve gear and higher pressure boilers. Despite this, the nickname stuck for many years after.

<span class="mw-page-title-main">Locomotives of the Great North of Scotland Railway</span>

The locomotives of the Great North of Scotland Railway were used by the Great North of Scotland Railway to operate its lines in the far north-east of the country. The railway opened in 1854 with just five 2-4-0 steam locomotives, and from 1862 it used 4-4-0 exclusively as the wheel arrangement for its tender locomotives. When it expanded by amalgamation in 1866, it inherited some locomotives from these companies. It purchased most of its locomotives, although building a small number itself, two at its first works at Kittybrewster, and ten later at Inverurie Locomotive Works.

<span class="mw-page-title-main">NBR A class</span>

The NBR A Class (London and North Eastern Railway Classes N14 and N15 were the standard 0-6-2 tank locomotives designed by William P. Reid for freight duties on the North British Railway. The LNER regarded the original locomotives as two separate classes. The final batch of locomotives was on order at the time of the grouping in 1923.

<span class="mw-page-title-main">LNER class D41</span>

The London and North Eastern Railway (LNER) D41 class was a type of 4-4-0 steam locomotive inherited from the Great North of Scotland Railway (GNSR). The class consisted of two similar GNSR classes: 'S' and 'T'. The two classes were similar but with detail differences to the boiler.
