The Class A4 is a class of streamlined 4-6-2 steam locomotive, designed by Nigel Gresley for the London and North Eastern Railway in 1935. Their streamlined design gave them high-speed capability as well as making them instantly recognizable, and one of the class, 4468 Mallard, still claims the...

Liveries

As with the other members of the 35-strong class, Sir Nigel Gresley wore many liveries throughout her career. She was released to traffic on 30 October 1937 in the standard LNER garter blue of the A4 Pacifics. New numbers and letters for the tender in stainless steel were added in a general overhaul 16 January 1939. Sir Nigel Gresley was repainted into wartime black with LNER markings on 21 February 1942. The next repaint was into black with NE markings on 20 October 1943, as a cutback. After the war, Sir Nigel Gresley regained LNER garter blue livery with red/white lining on 6 March 1947. With the formation of British Railways came new liveries and Sir Nigel Gresley was painted into British Railways dark blue with black and white lining on 27 September 1950. The final livery change was into British railways brunswick green livery on 17 April 1952. In preservation, Sir Nigel Gresley wore garter blue (with stainless steel letters and numbers as 4498 added later) from 1966 until her overhaul in the late 1990s, when she gained her current British Railways blue livery as 60007. This livery was retained again after the 2006 overhaul.

Technical Details

As with the earlier LNER A4 Pacifics, Sir Nigel Gresley was built with single chimney and side valances covering the wheels. The valances were removed to aid in maintenance on 21 February 1942. Sir Nigel Gresley gained her double chimney and Kylchap double blastpipe on 13 December 1957. 60007 also gained AWS (Automatic Warning System) equipment on 27 September 1950. A Smith-Stone type speed recorder was fitted on 30 June 1960.

Sir Nigel Gresley has had twelve boilers in her career: 8961 (from new); 8946 (from 4483 Kingfisher), 21 February 1942; 9489 (new boiler), 6 March 1947; 29271 (from 60024 Kingfisher), 27 September 1950; 29319 (new build), 17 April 1952; 29306 (spare), 19 October 1953; 29321 (from 60010 Dominion of Canada), 12 March 1955; 29314 (from 60026 Miles Beevor), 13 April 1957; 29324 (from 60015 Quicksilver), 13 December 1957; 29331 (new build), 16 April 1959; 27970 (new build), 7 October 1960 and finally 27966 (from 60016 Silver King), 25 October 1962.

Sir Nigel Gresley had two tenders in her career: 5329 from new build to 8 August 1943 and then 5324 from that time.

Locomotive 4498 was actually due to receive the name
Bittern, originally suggested for 4492 (later Dominion of New Zealand). So the story goes, an LNER enthusiast who worked in the Railway Correspondence and Travel Society, realised in time that 4498 was the 100th Gresley Pacific locomotive and the suggestion was made that the locomotive be named after her designer. The name Bittern

was later carried on 4464.

Sir Nigel Gresley was allocated to Kings Cross 'Top Shed' from new. As LNER locomotive 7, she was reallocated to Grantham on 23 April 1944, but sent back to Top Shed on 4 June 1950. Top Shed kept 60007 until the depot was closed, then Sir Nigel Gresley was reallocated to New England shed on 16 June 1963. Sir Nigel Gresley was then allocated to St Margarets shed, to work the Edinburgh - Aberdeen trains, until final shed allocation was to Aberdeen on 20 July 1964.

Sir Nigel Gresley received a repaint at Doncaster Works 25 February 1938, and larger coal space was also provided as the locomotive was displayed at an exhibition in Manchester. Sir Nigel Gresley was also used for the opening of the Rugby testing station from 23 August - 8 October 1948. 60007 was placed onto the rollers without her tender and run up to high speeds to monitor the coal and water usage of the locomotive.

Sir Nigel Gresley is the holder of the post-war steam record speed of 112 mph gained on 23 May 1959 and carries a plaque to that effect. As with Mallard

Preservation

Withdrawn from service by British Railways on 1 February 1966, it was targeted by the A4 Preservation Society, which was soon renamed the A4 Locomotive Society, to rescue the locomotive from the cutter’s torch. This was achieved, and the ‘Streak’ was moved to Crewe

For a long period of her preservation, Sir Nigel Gresley was kept at Steamtown Carnforth, at the old locomotive depot. This was a prime location for her mainline operations, being the only mainline A4 after 1973 other than Union of South Africa

after its winter overhaul in 2009/10 revealed that extensive work and repair was needed on the tubing.. However, in November 2010, repairs had been completed, and the locomotive is now running in regular service again. The first rail tour after this repair was The Great Britain IV, 16th April 2011.

However, in May 2011, during the routine annual boiler exam, small cracks were detected in the firebox. Initially it was thought that a repair could be performed using copper welding, but further inspection showed a more extensive repair would be needed and 60007 will not be operational until late October at the earliest.
