First run in 1937, the 4-6-2 Streamlined Princess Coronation locomotives were designed by William Stanier. Despite his opposition to the streamlined design, it went ahead anyway due to the wishes of the London, Midland & Scottish Railway which

wanted a streamlined locomotive to promote luxury and speed around the world.


The Caledonian Railway blue with silver horizontal lines is depicted here in the streamlined style that was applied to these powerful LMS locomotives when they were constructed at Crewe Works in 1937.


The first five locomotives, Nos. 6220–6224, were built in 1937 at Crewe. 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 reminiscent of an upside down bathtub and was fitted 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 gained at high speed.


The second five locomotives of the class, Nos. 6225–6229, were also streamlined, but were painted in the more traditional crimson lake, with gilt horizontal lining. This was to match the 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 the outbreak of the Second World War.


The next batch was built without streamlining. They were considered to be very handsome locomotives.

NEWCASTLE - YORK ROUTE


Coronation - Big Smoke

Drive 6220 Coronation from Newcastle to York on an express service from London.


Coronation - Auld Reekie

Drive 6222 Queen Mary on the 10:00 Kings Cross - Edinburgh service. Year: 1946.


Coronation - Last Minute Replacement

The Black 5 rostered for the 07:40 Darlington - Newcastle service has failed. You must take charge of 6223 on this extremely rare outing for a Coronation. (In RailWorks 2 this is a Timetabled Scenario and it can be tough to keep to the timings. However, it is possible to complete if you drive well!)
