Derek Dean's resolve in the compilation of this page with no prospect of financial gain, just the satisfaction of being involved, tells you a great deal about the man.
This led to the Locomotive Interchange Trials of 1948, supervised by RA Riddles, then member of the BTC's Railway Executive, who, along with ES Cox was responsible for the design and construction of twelve new classes to be numbered in the 70-80,000s and 92,000s in the fleet.
In 1951, the 'Britannia' Class 7MT Pacific became the first of twelve new British Railways Standard types to appear.
ENGINE BRAKE HOSES: The first 19 Britannia Class engines were built with a medium length stanchion pipe for the brake vacuum hose on the front of the locomotive as well as on the rear of the tender..image '1' below.
These could be seen on Nos 70000 to 70018 in their formative years, but were gradually modified from the early months of 1952 up to the start of 1955, with the tender hoses similarly treated..image '2' below The flexible ends to these hoses were blanked off by a secure clamping device which pulled the pipe flange down onto a stout rubber seal attached to the lower section of the stanchion pipe on the early types, but on the modified type, a stout bracket was bolted to the buffer beam and this held the hose securely onto a sealing ring, which was further protected by a securing pin attached to a short chain.
Please note Nos 70025-70054 are featured on the next page.
Born in 1946, Derek started train spotting with his brother Roger at the now-closed Monument Lane station, Birmingham, where he fondly remembers the '1 o'clock Brit' on the 9.30am Manchester-Birmingham, .
His research has taken him more than 3 years, and I was pleased he agreed to pass on his findings here However, Derek's main reservation was that, whilst the first group of Britannias are indeed very interesting, and in some cases diverse, the third batch of engines are somewhat mundane by comparison, and so whilst he felt confident of filling a page with information on say, Nos 70000-70024, it would be tricky to give the same result with 70045 to 70054.
This is because the list of modifications diminished as they were put into the building programme and only half of these changes were required on later batches.
In order to avoid duplication No 45700's nameplates were removed in 1951 and the engine named after HMS Amethyst, the Royal Naval vessel involved in the Yangste River incident of 1949.
Built at Crewe Works in April 1936, No 45700's shed allocations included Newton Heath, Blackpool, Bank Hall, Derby and Warrington; withdrawal came in August 1964.
Nevertheless there are many more photos of these later builds, primarily because enthusiasts began to realise that extinction was on the horizon, so perhaps the additional photos will remedy the imbalance.
