HOR R3860 Hornby BR, Merchant Navy Class, 4-6-2, 35012 'United States Lines' - Era 4- 2023 Catalogue
Conceived in 1937 when Oliver Bulleid became Chief Mechanical Engineer of the Southern Railway, the Merchant Navy Class represented Bulleid's vision for a quick accelerating, mixed traffic 4-6-2 locomotive, equally capable of hauling passenger services (such as the Golden Arrow and Atlantic Coast Expresses), or freight workings, to a speed of around 75mph.
Mainly designed from the Brighton Works Drawing Office, under C.S Cocks, Bulleid, always aware of the practical applications and costing implications ensured that the best design practices of the time were applied to the new locomotive. Like his mentor, Nigel Gresley, Bulleid was a technically arrogant CME, an advocate for locomotives being driven hard and to brisk schedules and this materialised in his design ideas.
In 1934, Bullied had been opposed to the use of streamlining but for the Merchant Navy's 'air-smoothed' design is suited his purposes, being easy to clean mechanically and hiding the boiler's external pipes, which in turn meant that they could be run for function, rather than aesthetics. Opting for a welded steel firebox, instead of traditional copper construction for reduced weight and pressure benefits, Bulleid was able to make the three equally sized cylinders smaller, at 18', and better balanced.
New X-ray inspection techniques were specifically developed to monitor wear to the welded areas, whilst the newly designed Bulleid Firth Brown 6" 2' driving wheels reduced the amount of hammer blow to the rails, also resulting in less wear. Of all the new features Bulleid incorporated into the design, perhaps the most ingenious and, ultimately, most controversial was his decision to totally enclose the valv
