THE A4 LOCOMOTIVE SOCIETY LIMITED

Sir Nigel Gresley

The A4 LOCOMOTIVE SOCIETY LIMITED ( A Company Limited by Guarantee ) was formed early in 1967 to take over by agreement the assets and membership of the A4 Preservation Society, which had been formed in 1964 with the object of preserving in full working order the former LNER class A4 Pacific locomotive No 4498 Sir Nigel Gresley. 4498 Sir Nigel Gresley was the 100th Pacific locomotive built to the design of Sir Nigel Gresley, the Chief Mechanical Engineer of the London and North Eastern Railway Company.

4498 was built at Doncaster Locomotive Works of the LNER, Works No 1863, and allocated to Kings Cross Shed, London on 30th November 1937. A naming ceremony had taken place on 16th November at Marylebone station. The nameplates were unveiled by William Whitelaw, the Chairman of the LNER, who also presented Sir Nigel Gresley with a miniature silver replica of the locomotive to commemorate the occasion.

No 4498 ran approximately 1 1/2 million miles in revenue earning service for the LNER and British Rail and was withdrawn from service in February 1966 as British Rail No 60007. During May 1966 the locomotive was purchased by the A4 Preservation Society for £4,500, the Society having raised the money by public appeal and from the proceeds of rail tours. The locomotive was transferred to Crewe Locomotive Works and after a full examination a major overhaul was commenced in August 1966 and this was completed in March 1967 at a cost of approximately £16,000.

The Society decided that the locomotive should be restored in the Garter Blue livery in which it was painted originally, bearing its LNER number 4498 and with modifications that had been made over the years to improve the performance of A4s. On 1st April 1967, the 'Inaugural Run' special train organised by the A4 Locomotive Society Ltd and the first train worked by 4498 Sir Nigel Gresley in the private ownership of the Society, ran from Crewe to Carlisle going over Shap and the return via Ais Gill and Blackburn. Near Weaver Junction, 16 miles from the start out of Crewe, 4498 reached a top speed of 92 mph with a remarkable performance for a loco so new out of shops. The Society officers had been told at Crewe that the loco was good for 110 mph after the overhaul had been done!

After the inaugural run, 4498 was used on a number of rail tours in 1967 until steam locomotives were banned from BR later in the year.

4498 was moved from Crewe to the National Coal Board depot at Philadelphia Co. Durham and was maintained there in full working order until April 1977. The second major boiler overhaul was carried out by the Society during this time.

In 1972 the steam ban was relaxed and since then 4498 has been actively engaged in running excursions on BR. A further major overhaul was carried out in 1983/84. Following this on returning to service, 4498 was taken to London for the launch of the Post Office Famous Trains railway stamps issue from the original paintings by Terence Cuneo on which 4498 was shown on the 1st class stamp (17p) hauling the Flying Scotsman train.

As a result of this visit to London 4498 was used by British Rail to launch the series of special trains steam hauled from Marylebone to Stratford upon Avon. This very successful enterprise led to the wider use of preserved steam locomotives in the developing leisure market, at the same time broadening the scope for steam traction on BR to satisfy the increasing demands of railway enthusiasts for new routes.

The Society was a founder member of the Steam Locomotive Operators Association which represents the interests of all privately owned steam locomotives that operate on BR and agrees with them the standards of maintenance that are required for safe operation on the main line.

The fourth major overhaul of 4498 was commenced in the autumn of 1989 at Steamtown, Carnforth and this work has been completed at a cost of approximately £135,000. Included in this programme was extensive renovation of the tender and the Society's support coach.

During the early autumn of 1994, it was decided to repaint 4498 in the BR standard express passenger blue livery, which the engine carried in the early 1950s as No 60007 and is unique on preserved main line locomotives. At the same time, opportunity was taken to celebrate the 35th anniversary of the world post-war speed record of 112 mph gained by 60007 on May 29th 1959. Alan Pegler, who was on the footplate when the engine achieved this record, unveiled commemorative plaques at the Great Central Railway, where the repaint was carried out.

A great deal of the work in carrying out an overhaul is done by the voluntary labour of members having the necessary skills to complete the many complex and arduous tasks. Other members give support by way of donations and loans. The Society is therefore always relying on members and new members are very welcome. 60007's home engineering base is at the East Lancs Railway at Bury.

Fact or Fiction

The US standard railroad gauge (distance between the rails) is 4 feet, 8.5 inches. That is an exceedingly odd number. Why was that gauge used? Because that's the way they built them in England, and the US railroads were built by English expatriates. Why did the English build them that way? Because the first rail lines were built by the same people who built the pre-railroad tramways, and that's the gauge they used. Why did "they" use that gauge? Because the people who built the tramways used the same jigs and tools that they used for building wagons, which used that wheel spacing. So why did the wagons have that particular odd spacing? Well, if they tried to use any other spacing, the wagon wheels would break on some of the old, long distance roads in England, because that was the spacing of the wheel ruts. So who built those old rutted roads? The first long distance roads in England were built by Imperial Rome for their legions. The roads have been used ever since. And the ruts in the roads? The ruts in the roads, which everyone had to match for fear of destroying their wagon wheels, were first formed by Roman war chariots. Since the chariots were made for Imperial Rome, they were all alike in the matter of wheel spacing. The US standard railroad gauge of 4 feet-8.5 inches derives from the original specification for an Imperial Roman war chariot. Specifications and bureaucracies live forever. So the next time you are handed a specification and wonder what horse's arse came up with it, you may be exactly right, because the Imperial Roman war chariots were made just wide enough to accommodate the back end of two war horses. Thus we have the answer to the original question. Now for the twist to the story. When we see a space shuttle sitting on it's launching pad, there are two booster rockets attached to the side of the main fuel tank. These are solid rocket boosters, or SRB's. The SRB's are made by Thiokol at their factory in Utah. The engineers who designed the SRB's might have preferred to make them a bit fatter, but the SRB's had to be shipped by train from the factory to the launch site. The railroad line from the factory had to run through a tunnel in the mountains. The tunnel is slightly wider than the railroad track, and the railroad track is about as wide as two horses' rumps. So, a major design feature of what is arguably the world's most advanced transportation system has determined over two thousand years ago by the width of a horse's arse!
