The Belfast and Northern Counties Railway Class B was a class of 4-4-0 two-cylinder compound steam locomotives that was introduced for passenger service in the north-east of Ireland during the late 1890s.
The Belfast and Northern Counties Railway (BNCR) in the north-east of Ireland had standardised on locomotives with a 2-4-0 wheel arrangement for its principal passenger locomotives during the 1870s and construction continued through to the mid-1890s. With increasing loads and heavier trains the limitations of that wheel arrangement became apparent and a new design was needed. In 1897 the first purpose-built 4-4-0s, the Class B "Light Compounds", entered service.
Built by Beyer, Peacock & Company in Manchester, England, the Class B was turned out as a 4-4-0 version of the Class C 2-4-0 that had been introduced during 1890-95. With the same type of boiler and identical cylinder sizes, it was no more powerful than the earlier design.
Two of the class, Nos.59 and 62 were "renewed" in 1924 as Class U1 4-4-0 locomotives although probably very little remained of the original engines except for their wheels and valve gear.
The other three members of the class received less radical rebuilding. Nos.60 and 61 were firstly rebuilt as Class B1 compounds following which they underwent further alterations to become Class B3 4-4-0s in 1932. No.24 was rebuilt as a simple to become the only member of Class B2 in 1925 and again to Class B3 in 1928.
The BNCR painted the locomotives "invisible green" (a very dark bronze green that looked almost black) with vermilion, light blue and yellow lining. The initials "BNCR" in block capitals were carried on the tender sides.
The livery remained the same under Midland Railway administration with the addition of the diamond-shaped Midland Railway crest to the cab sides and the initials "NCC" in gold block capitals on the tender sides. Buffer beams were vermilion, and the smoke box was black.
The Northern Counties Committee (NCC) was a railway that served the north-east of Ireland. It was built to Irish gauge but later acquired a number of 914 mm narrow gauge lines. It had its origins in the Belfast and Ballymena Railway which opened to traffic on 11 April 1848.
A wide variety of steam locomotives have been used on Ireland's railways. This page lists most if not all those that have been used in the Republic of Ireland and Northern Ireland. Irish railways generally followed British practice in locomotive design.
The Great Northern Railway V class steam locomotives were 4-4-0 three-cylinder compound locomotives built in 1932 by Beyer, Peacock & Company for the Great Northern Railway (Ireland).
The Lancashire and Yorkshire Railway Class 27 is a class of 0-6-0 steam locomotive designed for freight work on the Lancashire and Yorkshire Railway (L&YR).
The NCC Class WT is a class of 2-6-4T steam locomotives built by the Northern Counties Committee's parent company, the London, Midland and Scottish Railway for service in Northern Ireland.
The LMS Northern Counties Committee (NCC) Class Y was a class of 0-6-0T steam locomotives formed when two LMS Fowler Class 3F engines were regauged from 4 ft 8+1⁄2 instandard gauge to the 5 ft 3 in Irish broad gauge in 1944 becoming NCC Nos.18 and 19.
The Belfast and Northern Counties Railway (BNCR) Class A was a class of 13 two-cylinder compound steam locomotives built for service in north-east Ireland. The first two members of the class would be the last locomotives to be built for the independent BNCR, being completed before its purchase by the Midland Railway in 1903. The members of the class were rebuilt by the LMS (NCC) becoming either Class A1 or Class U2 depending on how they had been modified.
The Northern Counties Committee (NCC) Class U2 4-4-0 passenger steam locomotives consisted of 18 locomotives built for service in north-east Ireland. Ten of the engines were new builds supplied by the North British Locomotive Company (NBL) or constructed at the NCC's York Road works. The remainder were rebuilds of existing locomotives.
The Belfast and Northern Counties Railway (BNCR) Class S was a class of 2-4-2T two-cylinder compound steam locomotives that was introduced for service on the 3 ft narrow gauge railways of County Antrim in north-east Ireland.
Bowman Malcolm was an Irish railway engineer. He became Locomotive Superintendent of the Belfast and Northern Counties Railway (BNCR) at the age of 22 and later took on the additional role of Civil Engineer. He was an advocate of compound locomotives which he introduced to the BNCR.
The Northern Counties Committee (NCC) Class S1 was a class of two-cylinder compound 2-4-2T steam locomotives that was introduced for service on the 3 ft (910 mm) narrow gauge railways of County Antrim in north-east Ireland. The members of the class were rebuilds of the BNCR Class S.
The Northern Counties Committee (NCC) Class S2 was a solitary two-cylinder compound 2-4-4T steam locomotive that was introduced for service on the 3 ft narrow gauge railways of County Antrim in north-east Ireland. It was heavily rebuilt from a BNCR Class S locomotive by the addition of a standard gauge boiler.
The Northern Counties Committee (NCC) Class X was a solitary diesel-hydraulic shunting (switcher) locomotive built by Harland and Wolff (H&W) for service in the NCC's yards and at Belfast docks. It was one of several pioneering designs of diesel locomotive produced by H&W under their Harlandic trademark during the 1930s and 1940s.
The LMS (Northern Counties Committee)Class A1 4-4-0 passenger steam locomotives were rebuilds of Belfast and Northern Counties Railway Class A two-cylinder compound locomotives. They operated services throughout the NCC’s 5 ft 3 in (1,600 mm) broad gauge system in the north-east of Ireland.
The LMS (Northern Counties Committee)Class B3 4-4-0 passenger steam locomotives were rebuilds of Belfast and Northern Counties Railway (BNCR) two-cylinder compound locomotives. They operated services throughout the NCC's 5 ft 3 in (1,600 mm) broad gauge system in the north-east of Ireland.
The Belfast and Northern Counties Railway (BNCR) Class N was a class of 0-4-0ST dock engines that worked on the Belfast Harbour Commissioners' lines in north-east Ireland. No.42 was the first of the class and was built by Sharp, Stewart and Company in 1874. A second, similar engine, No.16, was built by the MR (NCC) in 1914.
A compound locomotive is a steam locomotive which is powered by a compound engine, a type of steam engine where steam is expanded in two or more stages. The locomotive was only one application of compounding. Two and three stages were used in ships, for example.
The London and North Western Railway (LNWR) Class B was a class of 0-8-0 steam locomotives introduced in 1901. A development of the three-cylinder compound Class A, they had a 4-cylinder compound arrangement. 170 were built between 1901 and 1904.
The Londonderry & Coleraine Railway is a railway line between the cities of Derry and Coleraine in County Londonderry, built by the Londonderry & Coleraine Railway Company (L&CR). The company operated the line independently for seven years before being absorbed into the Belfast & Northern Counties Railway. The line is still in use today by NI Railways and forms part of the Belfast to Derry-Londonderry rail line.
