Steam Train Model Locomotive Duchess of Montrose 46232 BR Hornby 1:120 Scale TT. The story of the Princess Coronation Class is one of split personalities and purposes. The original streamlined form of the class arose from tests on Stanier’s development of the Princess Royal class locomotives. When the opportunity to produce five conventional versions of the Coronation Pacific as a comparison to the streamlined version arose, Stanier was quoted as saying,’They can have their streamliners if they b want them, but we will also build them five proper ones’ such was his lack of interest in a streamlined locomotive specifically. Those first five conventional locomotives were 6230 Duchess of Buccleuch to 6234 Duchess of Abercorn, colloquially known as Duchesses, after the first of this sub-class. Appearing in 1938 with a single chimney and without smoke deflectors, many purists regard these as the finest Pacific locomotives ever produced. Originally ordered as streamlined, the demands of maintaining the streamlined form exceeded the cost savings in coal and so they emerged from works without the casing, but with streamlined tenders (which had been completed before that decision was taken). The process of de-streamlining the remaining engines began with 6235 City of Birmingham in April 1946, with 6243 City of Lancaster being the last in May 1949. Locomotives that had streamlining removed had a distinctive slant to the leading edge of the top of the smokebox, where this was previously hidden by the panels and designed to accommodate them. Eventually the raked smokeboxes were replaced with conventional smokeboxes, so that by late 1958 the majority of the fleet showed a similar appearance for the first time. Duchess of Montrose entered service in 1938 in the LMS’ well known Crimson Lake livery being numbered 6232. It would wear this livery and number for the entire time it would serve with the LMS before being adopted into BR as 46232 in 1947. Under BR Duchess of Montrose would wear three different liveries, before being scrapped in November of 1963 at Crewe. Item Length – Without Packaging (cm). Item Height – Without Packaging (cm).
