The National Lottery Heritage Fund Bid Outcome

We announced at our Annual General Meeting in June 2024 that we met the deadline and submitted our highly detailed National Lottery Heritage Fund (NLHF) Stage One application. The application was completed along with our strategic application partners; The Swindon and Cricklade Railway, and our planned home for main line running The Yeovil Railway Centre.

The board thanks all our members that assisted with the funding of the Stage One application.

Unfortunately, we have been advised that our stage one bid has been rejected on the basis that the proposed programme, planned within the constraints of the NLHF’s guidelines, would, in their opinion, take much longer and cost considerably more. This would place the long term sustainability of the project at risk. The bottom line was that the substantial cost of our project, together with its complexity and inherent high risk, did not represent value for the NLHF.

Whilst we can’t go forward with this application the NLHF has stated they would be happy to offer us advice with a smaller, less complex and lower risk project. We are therefore already in discussion with the NLHF regarding the viability of a 2nd application that, alongside the engineering work, would place an emphasis on community engagement, young people, skills development, apprenticeships and diversity. The NLHF recognised the quality and detail of our application and submitting a scaled down and less complex application should not incur much additional cost.

Whilst the outcome is of course disappointing, the vast amount of work and content that was completed and necessary for the bid is just as relevant and necessary for the project going forwards and puts us in a stronger position than we were prior to making the bid.

The board is currently reviewing the future structure, personnel and options for the project and initiating discussions with both existing and potential new strategic partners.

We aim to provide more details of the strategic plan for the future and progress on engineering in the next issue of the members magazine The Packet.  We will also confirm if our follow up conversations with the NLHF have been constructive and will result in us pursuing a 2nd application. Our initial EOI was rejected, and we were invited to make some changes and resubmit, which led to a pass at that stage.

Whilst the outcome is of course disappointing, we reiterate that the work, content and involvement of our strategic partners within the application is hugely beneficial to the project and the current board remain committed to the aim of recreating General Steam Navigation to her original as-built condition complete with air smooth casing and Bulleid’s unique patented chain driven valve gear.

General Steam Navigation welcomes visit by Justin Tomlinson, MP for North Swindon

General Steam Navigation CIC (GSNCIC) welcomed Justin Tomlinson, MP for North Swindon, who visited Blunsdon at the Swindon & Cricklade Railway to view 35011 General Steam Navigation and discuss the current application to the National Lottery Heritage Fund.

The application is focussed around the reconstruction and restoration of the Merchant Navy Pacific to original Bulleid condition, making it unique in preservation. Whilst the work on 35011 meets the “Saving Heritage” element of the bid, the other key Heritage Fund investment principles will be partially addressed with a new building at Blunsdon (which will be a Swindon & Cricklade Railway asset) to encompass engineering facilities together with training and education spaces.

L to R – Jon Netting (Treasurer – General Steam Navigation), Cllr Matt Vallender, David Tucker (Heritage Consultant), Justin Tomlinson MP, Robert Battersby (Architect), Nigel Willoughby (Trustee S&C Rly), Cllr Mark Clarke, Cllr Jason Mills, Gerry Leyman (Chair – General Steam Navigation CIC), Mike Abbott (Chair – S&C Rly).

Justin was accompanied by 3 local councillors, Mark Clarke (Cricklade Town), Matt Vallender and Jason Mills (Swindon Borough).

Following the visit Justin said “We will all be working together as they prepare their National Heritage Lottery fund bid. The Swindon & Cricklade Railway is a much loved and popular local service, so I have no doubt there will be strong local community support for this bid.

I have fed in a number of suggestions on how to strengthen the bid including working with a wide a range of local community groups, including all the local schools, Parish Council’s and the Wiltshire Wildlife Trust.

As someone from a family of steam enthusiasts, I am very excited to be supporting this fantastic bid”.

Autumn Engineering Update

Autumn Engineering Update

 

Welcome to this autumn engineering update from the General Steam Navigation project.  Progress has been made on various engineering fronts on the project over the past few months and with some of our background efforts about to bear fruit we’ll have some brilliant work to share over the coming months.

Boiler

The boiler tubes are gone! After many months of hard work by our small band of volunteers, the job is done. Work has continued on removing rust from the inside of the firebox, descaling the inside of the boiler, and generally cleaning the inside of the boiler and firebox ahead of a planned inspection later this year. Still to do is sourcing the right tool for removing the thermal-syphon inspection plugs, so that we can wash out the boiler, and then plan the inspection.

Crank axle

Progress with the crank axle has been limited in the past few months; geopolitical events has caused the price of steel to become volatile, after discussions with our friends in the B17 project & A1 Steam Trust, with whom we were planning to place a group order for A4T forgings for the stub axles, we are pausing the ordering process until we have greater certainty over the price. Whilst it is disappointing to not be placing an order for these crucial parts of our locomotive, it feels more prudent to wait, saving us money in the long run. During this self-imposed delay, we are using the time to produce the engineering justification for manufacture of the stub axles in A4T & the sweep webs in 817m40, so that when we are happy with prices, we can proceed.

Frames

Work on the frames continues at a good pace with our volunteers working hard to clean up the frames in preparation for assessment of their condition. With over 50 years of grime to remove on the frames its not a particularly glamorous job but is very important and we are extremely grateful to all our hard workers. We have also removed the brake cylinders from the frames as they wont be required for an original condition Merchant Navy. The cylinders will be cleaned up and stored should a rebuilt Bulleid require them in the future.

Sponsorship component of the month

For those that want to make a more tangible contribution towards putting the steam back in General Steam Navigation we have relaunched the ‘Component Sponsorship’ scheme.

Each month the Society will highlight one particular component. The scheme will allow generous sponsors to cover the cost of individual parts that range from few pounds to several thousands.

Our generous sponsors will receive a certificate describing the part sponsored, be named on the roll of honour on this website and gracious thanks from all those who wish to see General Steam Navigation back in operation.

This month we are starting with the steam chest covers for the outside cylinders. The steam chest covers are a relativity simple component to produce being machined from plate steel.  35011 will require 4 of these in total with the covers being fitted to the front and rear of the cylinder on both sides .The cost of these covers are £250 each. For a full list of the currently available component and how to sponsor them please visit the component sponsorship page. 

Draughting


The question that has been asked a few times, both within our project, and outside it, is why we are considering modifications to the exhaust, especially as Bulleid pacifics had a reputation for being free-steaming, if hungry locomotives. The reason is buried in that last statement. Consider how a steam locomotive, especially its combustion system works: exhausting steam in the smokebox produces a draught, sucking air into the firebox for the coal to burn. How much air the locomotive supplies to the fire will impact its fuel combustion. Too little, and you have rich combustion, which releases a lot of heat from the coal, but at the expense of high fuel consumption. Too much air, and you have overly lean combustion, which is cleaner (less production of carbon monoxide), but it can lead to high fuel consumption as well, as the extra air cools the hot air from the fire, reducing the heat transferred to the water in the boiler, meaning more coal is needed to be burnt to produce the same heat transfer to the steam. The reputation, coupled with data from the Rugby reports, suggests that at most of the steaming rates GSN is likely to operate, the combustion is too rich. The perfect air:fuel mass ratio for stochiometric combustion of coal is approximately 11.2:1. It is normal to supply more air than is necessary, to ensure all of the fuel sees sufficient air, normal practise for combustion of coal is to have approximately 30% extra air, so the ratio becomes 14.6:1. Data from the Rugby reports show the original locomotives ran with a ratio of between 11:1 & 17:1, with drop off in performance for steaming rates above 18,000lb/hr, which is where we can expect to operate. The rebuilt design exhaust was much less variable to incomplete combustion, and had higher air:fuel ratio. The data also suggests that these locomotives need to run with significant excess air, far more than the 30% recommendation. The rebuilt design can actually be seen to be broadly similar to how 71000 operated in BR service, suggesting that we can achieve similar performance with 35011 if we can emulate the performance of 71000s twin Kylchap design. By redesigning the exhaust, we should be able to achieve two things: (1) maintain closer to 50% excess air across the power range, reducing fuel consumption and (2) increase the total flow area of the blast nozzles, reducing the cylinder back pressure.

New Mainline Steam Builders Group starts work

The General Steam Navigation Locomotive Restoration Society is one of six high-profile steam project groups with the common objective of delivering their respective locomotives fit for UK mainline running that have agreed to meet and cooperate with each other on a regular basis.

While the groups all have their own technical and project management challenges to deal with, many of the present-day safety certification and related requirements are to some degree of a generic nature, applicable to all new or restored steam locomotives. Group members can also build on the collective knowledge in the new build sector, and the significant experience / expertise gained by the A1 Trust through the previous approval of Tornado; helping each other by sharing information and experience.  While the main focus will be on meeting the risk management and network compatibility requirements of the rail industry safety certification standards, other directly related issues (for example supplier assurance, technical solutions) will be under discussion. Sharing third party costs where appropriate can ease pressure on individual project budgets.

Founder Group Members are:

B17 Steam locomotive Trust
Class G5 Locomotive Company
General Steam Navigation Locomotive Restoration Society
LMS-Patriot Company
P2 Steam Locomotive Company (A1 Steam Locomotive Trust)
Standard Steam Locomotive Company (72010 Hengist)

The Group decided to come together as the benefits became clear through their individual project experiences.

An inaugural meeting was held on 26th January 2022 at the premises of CTL Seal Ltd, a large bespoke engineering company in Sheffield that is now the home of the B17 and Hengist projects.   With the expert guidance of Graham Nicholas from the P2 project (sharing direct experience from the A1 project and his work for the Railway Safety Standards Board), along with representatives of Ricardo Certification Ltd, the group studied the evolution of rail industry certification requirements up to the present day, before starting work together on a hazard identification exercise for heritage steam locomotive design and manufacture / restoration.

General Stream Navigation limited edition 00 gauge open wagons wagon in cooperation with the Medway Queen Preservation Society.

Continuing the cooperation between the General Steam Navigation Locomotive Restoration Society and the Medway Queen Preservation Society (a GSN shipping Co ship) following the success of their previous wagons in both 00 and N gauges further new limited edition 00 gauge 7 plank open wagon have been produced to raise fund for both societies.

The model has been produced by Dapol and is based on their 00 gauge 7 plank open wagons with the lettering General Steam Navigation, Blunsdon & Gillingham Pier (the locations of the two Societies) and Number 22. The wagon is available in either black or green, both colours that were carried by 21c11 General Steam Navigation during her lifetime. The wagons include a coal load.

The wagons cost £12.90 each and are available from the General Steam Navigation website online store here.

A small number of the previous limited edition N Gauge Gun Powder Vans in either red or blue are also still available for £11.90 whilst stocks last.

Hornby: A Model World’ new TV series to air on Yesterday TV Monday 11th October and features 35011 General Steam Navigation Locomotive Restoration Society.

Hornby: A Model World’ will be coming to your TV screens on Monday 11th October at 9pm on Yesterday Channel as the first episode of the ten-part series goes live!
The new UKTV Original series features behind the scenes action at Hornby HQ, of what goes into making Hornby, Airfix, Scalextric and Corgi models.

From century old steam engines to cutting edge racing cars. Each programme follows the process from drawing board to perfect mini replica. The series observes the ups and downs of the design process as Hornby  attempt to get the all important detail spot on, whether it is perfecting the sound of a 1930s steam loco or the stitching on a First World War fighter plane.In the first episode, the Hornby team go back to their illustrious past when they decide to launch a metal diecast replica of a 1940’s steam locomotive, our very own  Merchant Navy, 35011 General Steam Navigation. It’s a passion project for Development Director Simon Kohler who fondly remembers his brother getting one for Christmas as a child.
UKTV cameras visited one of our working weekends earlier this year to feature our project to restore 35011 General Steam Navigation back to original air smoothed condition complete with Bulleid’s patented chain driven valve gear to view our progress in the restoration of the full size version of Hornby’s model.

General Steam Navigation Locomotive Restoration Society awards contract for Trailing Truck restoration and confirm the grade of steel for new crank axle.

At the Annual General Meetings of the General Steam Navigation Locomotive Restoration Society (GSNLRS) and General Steam Navigation CIC we were delighted to announce that following the removal of the trailing truck from the frames in October 2020 and months of preparatory work by their hard working volunteers, that the restoration contract for the trailing truck has been awarded after a tender process to North Norfolk Railway Engineering.

Located at Weybourne Engineering works, North Norfolk Railway Engineering presented a strong bid for the work, with a high level of engineering detail, that respects the historical merit of the unique in preservation fabricated Merchant Navy trailing truck.

Originally fitted to a series 3 Merchant Navy, our fabricated trailing truck is the last survivor of its kind. Lighter than the cast truck fitted to the other preserved Merchant Navy locomotives, longer than a Light Pacific’s truck, the GSNLRS are having this unique piece of Bulleid locomotive design restored to mainline standard, a crucial step towards GSNLRS’s vision of an original Merchant Navy with original air smoothed casing and Bulleid’s patented chain driven valve gear.

Funding for the Trailing Truck restoration has been via our Trailing Truck Transformers Fund Club and ‘Lots’ being available for purchase to join the club. Membership of our Trailing Truck Transformer Fund Club is still available, for details click here.

Crank Axle Steel Selection

Since 1966, 35011 has been without it’s central crank axle. Alongside the missing valve gear, this has been the driving force behind the decision to return to original design condition, due to the cost of replacement to either design being similar.
After many years of behind-the-scenes research in the BPLA collection & National Archive in Kew, and recent detailed Finite Element Analysis conducted at the University of Birmingham, under the supervision of Professor Karl Dearn, has demonstrated that A4T steel is of a suitable grade for the correct balanced crank axle design for 35011 in original design condition.

The stress report of the balanced design maximum stress reduced by 23%

This means the GSNLRS can proceed to final design of the central axle & balancing of the motion, and the order placement for the steel in the coming months and moving the project further forwards to a functioning original Merchant Navy once more.
