The Princess Coronation Class is a class of express passenger steam locomotives built by the London Midland and Scottish Railway (LMS) and designed by William Stanier. They were an enlarged version of the LMS Princess Royal Class. Several examples were originally built as streamlined, though this was later removed. The non-streamlined locomotives were often referred to as the "Duchess Class". To enginemen they were all known as Big Lizzies. It is widely held that they were the most powerful passenger locomotives ever to serve on the British railway network. Image File history File links 6233_sans_blinkers. ...

Overview

The first five, 6220-4, were built in 1937. They were streamlined and painted Caledonian Railway blue with silver horizontal lines to match the Coronation Scot train they were built to haul. The streamlining is probably best described as like an upside down bathtub and was largely for publicity reasons- Stanier, the designer of the Locomotives felt that the added weight and difficulty in maintenance due to the streamlining was too high a price to pay for the actual benefits at high speed. The second five, 6225-9, were also streamlined, but painted in the more traditional crimson lake, with gilt horizontal lining. This was to match standard LMS stock and a planned brand new Coronation train made up of articulated coaches. Although a prototype for this was built and exhibited in America it was never put into service due to WW2. The next batch was built un-streamlined. They were considered to be very handsome locomotives. Smoke deflectors were added from 1945 due to drifting smoke obscuring the crew’s forward vision. War interrupted the building of the locomotives, but given the dire shortage of express motive power several more were then finished during the war and turned out in unlined black. 6253-57 were turned out in the 1946 LMS lined black and 46257 was turned out in BR black. Two locomotives to a modified design by George Ivatt were built in 1947 (6256) and 1948 (46257). The Caledonian Railway was a Scottish railway company which was grouped into the London Midland and Scottish Railway by the Railways Act 1921 in 1923. ... The Coronation Scot was a named express passenger train of the London, Midland and Scottish Railway inaugurated in 1937 for the Coronation of King George VI which ran until the start of the war in 1939. ... A bathtub A bathtub (AmE) or bath (BrE) is a plumbing fixture used for bathing. ... German soldiers at the Battle of Stalingrad World War II was the most extensive and costly armed conflict in the history of the world, involving the great majority of the worlds nations, being fought simultaneously in several major theatres, and costing tens of millions of lives. ... Henry George Ivatt (4 May 1886 — 4 October 1976) known as George Ivatt, was the post-war Chief Mechanical Engineer of the London Midland and Scottish Railway. ...

Single chimneys were fitted to 6220-6234 when built but they were replaced with double chimneys between 1939 and 1944. 6235 onwards were built with double chimneys. Smoke deflectors were fitted from 1945 with the last 5 carrying them from new.

An unusual feature of the tenders was that they were fitted with a steam-operated coal pusher to bring the coal down to the firing plate. When this was in operation a plume of steam could be seen rising from the rear face of the coal bunker backwall.

De-Streamlined Locomotives

The streamlining was removed from the fitted locomotives from 1946 onwards. It had been found to be a little value at speeds below 90mph, and was unpopular with running shed staff. Only 3 were still fitted at the end of the LMS period and they had been stripped by the end of 1949. Only 46243 City of Lancaster carried its British Railways number whilst streamlined.

Initially de-streamlined locomotives could readily be recognised by the sloping top to the smokebox. All were eventually replaced with fully round smokeboxes. The sloping top led to the train-spotters nickname of Semis (i.e. semi-streamlined).

Liveries

The livery history for these locomotives involves no fewer than 11 variations.

LMS Streamliner – Blue, Red, Wartime Black

LMS Non-streamliner – Red, Wartime Black, 1946 Black

BR Experimental – Blue, Black

BR Standard – Blue, Green, Red

BR Blue was carried by 25 of the 38 locomotives; the first 2 being so painted in May 1949, one locomotive is known to have carried the blue livery until June 1954. All locomotives carried Green. Only 16 locomotives were painted BR Red and these were allocated to the London Midland Region, Scottish allocated locomotives remained Green.

Preservation

Three Duchesses have survived. (4)6229 Duchess of Hamilton, (4)6233 Duchess of Sutherland have both seen action on main line railtours. Duchess of Hamilton, now out of working order, is in the process of a Steam Railway appeal to have her restreamlined. The third, (4)6235 City of Birmingham was the centrepiece in the, now defunct, Birmingham science museum. 46235 was put in place and the museum built around her. Vacant Science Museum, formerly Elkington Silver Electroplating Works The now defunct Birmingham Science Museum, or Museum of Science and Industry, previously the Elkington Silver Electroplating Works, is a building on Newhall Street in Birmingham, England. ...

Following a successful appeal run by Steam Railway Magazine, 46229 is to be re-streamlined. The locomotive has been moved to the Birmingham Railway Museum at Tyseley, where the work is being carried out. The project will be completed by July 2007, when the locomotive will return to York for the 70th anniversary of the Coronation Scot service - taking her place at the heart of a new National Railway Museum temporary exhibition. The Birmingham Railway Museum Trust in Birmingham, England operates two subsidiaries: Tyseley Locomotive Works and Vintage Trains. ...
