York Society of Engineers Lecture
Nº4498 Sir Nigel Gresley was the 100th Gresley Pacific built by the Great Northern Railway / London and North Eastern Railway. The locomotive was built at Doncaster, works Nº1863, entering service in 1937, following a naming ceremony at Marylebone Station on 26th November. The locomotive was mainly based at London King's Cross with a spell at Grantham during World War II. The locomotive was briefly re-numbered as Nº7 before becoming 60007 when the LNER was merged into British Railways. On 3rd June 1956 Sir Nigel Gresley had the honour of hauling the Royal Train from King's Cross to York with H.M the Queen on board. The 'Stephenson Locomotive Society Special' on the 23rd May 1959 was the first train in the UK with a booked or advertised schedule of over 100 m.p.h. and on that trip 60007 set the official post-war speed record for steam traction of 112 mph. In 1963 the locomotive moved to Scotland and was used on express services between Aberdeen and Glasgow.
60007 continues to be certified for mainline operation and over the years has been fitted with a range of modern safety and signalling equipment including the fitting of Air-Braking, On-Train Monitoring and Recording equipment and Train Protection & Warning System. On 5th July 2008 the locomotive hauled a 510ton load up the 1 in 200 / 1 in 178 of Stoke Bank with a minimum speed at the summit of 69.75 m.p.h., and in so doing achieved an output power of around 2500 IHP, considered an equal of some of the finest performances of the A4 class locomotives throughout their lives.
Sir Nigel Gresley is presently undergoing a 10 year general overhaul at the NRM workshop in York; the work is being carried out by the SNGLT engineering team. At the conclusion of the overhaul it is the Trust's intention that the locomotive will once again operate on mainline rail tours and heritage railways throughout the UK.
In his talk, Darrin will cover:
- A brief history of locomotive 60007 Sir Nigel Gresley, the owning trust and the company contracted to undertake the overhaul of the locomotive.
- The objectives of the overhaul – why we do it.
- Planning, management of tasks, recording and communication.
- Quality control, compliance and certification.
- Description of the workforce and the Engineering Team.
- Details of the actual work carried out including case studies and the challenges faced by an organisation of our type.
- Planning for future challenges.
- Educational activities.
Tea and coffee from 7.00pm.
Darrin Crone is a mechanical engineer who started his career in a fabrication yard on Teesside building North Sea Oil rigs. He eventually became Head of Engineering at an instrumentation and control system manufacturer. After volunteering on steam locomotives for over 10 years in his spare time he took the opportunity to lead the overhaul of a mainline network certified steam locomotive – a dream come true?
