3442 was completed at Darlington in July 1938 and was initially named MacCailein Mor but it was renamed The Great Marquess very soon afterwards.
The Great Marquess spent most of its working life based at Eastfield from where it worked on the West Highland line to Mallaig via Fort William. In December 1959 it moved to Dunfermline Upper where it was based until it was withdrawn from service in December 1961.
Following withdrawal from service it was purchased in 1963 by Viscount Garnock (later the Earl of Lindsay) who had worked for the LNER earlier in his life.
The locomotive was then overhauled at Cowlair Works where it was returned to LNER apple green livery.
In April 1963 it worked a special goods train to Neville Hill depot in Leeds where it then remained for the next nine years.
After having the locomotive overhauled it operated it hauled railtours on the BR network from May 1963 until April 1967 when it was withdrawn for boiler repairs after which it was stored at Leeds Neville Hill. The imposing of the steam ban in 1968 meant that it remained in storage there until September 1972 when it was moved to the Severn Valley Railway (SVR) where it was stored until 1980 when it was overhauled. By the early 1970s, Viscount Garnock was already associated with the fledgling SVR, being a non-executive Director of both the original Severn Valley Railway Company and its successor, SVR(H), from incorporation in 1972.
Steaming was achieved in 1973 with 200 miles being recorded. However, the locomotive’s axle weight in excess of 19 tons exceeded the limit of 17 tons 12 cwt in the SVR’s Light Railway Order granted in May 1970. The locomotive was therefore stored while discussions took place over a possible transfer to another railway. In the meantime a program of work was underway to upgrade the line, as a result of which the locomotive remained at the SVR.
The Great Marquess was next steamed in 1989, appearing in LNER livery as 3442. In early July The Great Marquess set off for a fortnight on the West Highland Line between Fort William and Mallaig. In 15 July the Earl, although ill (he died 16 days later), rode on the footplate of his engine as it departed from Fort William.
The following years saw the Great Marquess on a regular stint of main line railtours, interspersed with periodic returns to the SVR for repairs and working on the SVR itself. At the end of 1997, shortly after being repainted into BR livery as 61994, the locomotive suffered a failure of the crank axle in Bewdley tunnel, and joined the queue of locomotives at the SVR requiring repair. The cause of the problem was diagnosed to the valve settings with the inside and outside valve gear fighting themselves which applied a slight twisting motion on the crank axle.
In April 2003 The Great Marquess was bought from the family of the late Earl of Lindsay by John Cameron on condition that the locomotive returned to Scotland and be painted back in the LNER apple green livery. Plans were announced for an overhaul and repair of the driving axle at the SVR. However, it transpired that the overhaul could not be completed in the timescale required by the new owner, and The Great Marquess left the SVR in spring of 2005 for overhaul at Crewe but was outshopped in BR lined black livery which it has carried ever since.
Since returning to steam after overhaul it was visited many heritage railways and continued to operate on mainline charters. The Great Marquess is normally based at Thornton Junction.
In October 2015 it was taken out of service as it needed firebox repairs and its boiler certificate expired in May 2016.
The owner has indicated 61994 may not steam again and may be housed in a new museum he plans to build in Fife. Prior to this museum being opened the locomotive will go on display at the Bo’ness & Kinneil Railway. It was moved by road from the North Yorkshire Moors Railway to its new temporary museum in September 2017.
In November 2022 it was reported that approval had been given for the construction of the home for the locomotive at the farm of John Cameron in Fife. The timetable for moving this locomotive and 60009 Union of South Africa to Fife is not yet known.
By May 2023 60009 Union of South Africa and 61994 The Great Marguess were housed in the John Cameron Museum in Fife but were not on public display
