Winter Engineering Update

Work on General Steam Navigation has progressed at a pace over the last few months with our regular working parties at Blunsdon. The majority of the work has been focused around 35011s chassis in preparation for “crane day” that happened in November. With the help of our friends at the Swindon and Cricklade Railway steam department our volunteers were able to successfully remove the five frame hangers that won’t be required in the restoration of  General Steam Navigation back to Bulleid’s original condition.
These components were: the slidebar bracket hangers (these were heavily modified upon rebuilding due to the outside valve gear) and  outside motion brackets on each side; along with the screw reverser bracket on the left hand side.
In the spring of next year it is planned to remove 35011s remaining wheels and front bogie in order to enable a full assessment of her frames to be undertaken.

Preparation work for producing the components required for the chassis and the alternations to the existing metalwork is being undertaken at the moment. This will enable the work to restore the rolling chassis to be only limited by the amount of money that can be raised to pay for the work. To help this work the Society has set up a “Putting Funds into  the Frames” appeal which enables people to donate as little or as much to the project with the guarantee that it’ll be spent on the frames.  You can find out more here.

Supporters will be aware that when we lifted the boiler from the frames in October last year, we also lifted the rear of the frames to release the Trailing Truck. Since then, work has been undertaken to remove the majority of the components that make up the Trailing Truck.
Following an independent assessment, we undertook a competitive tender process and in August we awarded the contract for the full refurbishment, and certification of the Trailing Truck by specialist contractors North Norfolk Railway Engineering (NNE).The Trailing Truck left Blunsdon and arrived safely at NNE Weybourne on the 10th October.

The Trailing Truck at the North Norfolk Railway

Since then North Norfolk Engineering have provided the following update of their activities:

• Completed the dismantling of the main component parts, with the truck chassis now lifted off the wheelset in readiness for the complete set of main parts and wheelset being sent away for shot blasting.

• Undertaken a series of key dimensional measurements to assess the general condition and wear levels ahead of developing the engineering overhaul strategy.

• Removed the seized main pivot pin out from its bronze bush and assessed the reason for it seizing, as the bush appears has moved during its working life  and rotated in the frame boss, blanking off the grease hole in the process, reducing lubrication.

The next key stage is to undertake Ultrasonic Axle Testing (UAT) of the axle and the axle to wheel interfaces to verify that no flaws are present. It will be carried out by a Rail Industry approved axle specialist early in the new year (at the same time as the annual check of all locomotives on the North Norfolk Railway to minimise cost).We are in the process of arranging the purchasing new suspension coil springs and are currently working with various suppliers. To help fund the restoration of the trailing truck the Society is offering a maximum of 30 members the opportunity to purchase a ‘Lot’ for £500. Members are welcome to purchase as many ‘Lots’ as they wish up to the maximum target amount.

Members of the Fund Group would receive a number of benefits including:

  • Certificate of membership of the ‘Trailing Truck Transformers’
  • Name engraved on a suitable brass plaque attached to the refurbished Trailing Truck
  • Regular updates on the refurbishment of the Trailing Truck
  • An invitation to a VIP day at the Swindon and Cricklade Railway to see the completed Trailing Truck once it is returned to the railway.

CME with students on Boscastle

In November our CME Dr Steve Rapley  took a group of students from Loughborough University to look at the smokebox and exhaust of 34039 Boscastle. This was to aid their understanding of the geometry they’re studying as part of developing the Internal Aerodynamics and draughting of 335011 General Steam Navigation Locomotive Restoration Society.  The Society would like thank Andy Morgan and Mike for hosting us.

You can find out more about previous projects undertaken with Loughborough and Birmingham Universities can be found here.

Progress continues with the boiler, there are still some stubborn ends of tubes to remove, but it is down to a handful now. Sterling work by our volunteers (including Paul G, David O, Geoff A & Jack G) continues with this strenuous task, with the expectation that the remainder will be out in the coming months. Work has started on removing rust from the inside of the firebox, and generally cleaning the inside of the boiler and firebox ahead of a planned inspection early next year. It may seem that one paragraph seems like little progress on the boiler, but this work is very labour intensive, and with only a small band of volunteers, maintaining Covid safe practices, it takes time for the fruit of their labours to become apparent.

In order to keep moving forwards with our restoration activities, the society is looking for a qualified railway mechanical engineer, preferably with welding experience or weld design experience, to advise the CME & Engineering Sub-committee in this field. If you fit this description, or know someone who does, please get in touch with us via info@35011gsn.co.uk

The momentum being generated by our engineering team means 2022 is going to be a very important year for the project with some big goals in mind. To achieve this we will need your help, you are able to support us in many ways if you are not already a Society member you can sign up for membership for currently only £15 per year here, or donate to the Society here or even better become a shareholder here.

As always thank you for your continued support.

GSN collaboration with Loughborough University continues

Last week our Chief Mechanical Engineer took a group of students from Loughborough University to look at the smokebox and exhaust of Bulleid Light Pacific 34039 Boscastle that is currently undergoing overhaul on the Great Central Railway.
This was to aid their understanding of the geometry they’re studying as part of developing the internal aerodynamics and draughting of our 35011 General Steam Navigation.
Following the success of the 2020/21 Loughborough University collaboration projects  we are running further projects in 2021/22 to look at aspects of the blastpipe design in more detail.
The intention is to compare the potential performance of a Bulleid-Lemaître blastpipe with other concepts such as the Giesl and Lempor ejectors.

Thanks to Andy Morgan and Mike for hosting us.

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.

35011 General Steam Navigation fund opened for the transportation and tyre profiling of the bogie and trailing truck wheelsets.

On 2nd October 2020, the boiler of Ex-SR Bulleid Merchant Navy Class, 35011 “General Steam Navigation” was successfully lifted from its frames for the first time since 1959 and the separation of the trailing truck from the frames. The General Steam Navigation Locomotive Restoration Society is now seeking funds to help overhaul the front bogie and trailing truck wheelsets.

35011 General Steam Navigation boiler lifted for the first time in 61 years – a major milestone reached in the restoration project.

On 2nd October 2020, the boiler of Ex-SR Bulleid Merchant Navy Class, 35011 “General Steam Navigation” was successfully lifted from its frames for the first time since 1959.

The boiler was built by North British in Glasgow in January 1941 and has been attached for a total of 61 years since its last overhaul in July 1959.

The lift of the boiler followed a successful fund raising “sponsor and inch or more” campaign and prize draw to cover the cost of the suitable crane hire to lift the boiler.  A fully tubed boiler weighs 24 tonnes,  however the tubes, despite the restrictions due to Cocid-19,  were removed by volunteers of the society reducing the weight to around 20 tonnes.

“It’s a very exciting time for everyone involved in the 35011 General Steam Navigation restoration project,” said Andy Collett Chairman of the CIC. “The removal of the boiler is a big turning point as it allows us to commence the restoration of the chassis, which will be a big project in itself, taking several years to complete.”

Vice Chairman of the Swindon & Cricklade Railway, Allan Bott welcomed the positive news. “It’s great to see 35011 take the next big step in its restoration journey. It brings a much-needed boost following our forced closure due to COVID-19. With the line re-opening to passenger services on Sunday 4th October, our customers can now come and see 35011’s progress following the successful boiler lift.”

Work on 35011 will now be directed to the restoration of the chassis and further fund-raising campaigns will be launched in due course.

 

Summer Engineering Update

Summer engineering update

In June a few select volunteers restarted  stripping down work on GSN. Numbers are being strictly limited to begin with to comply with social distancing so it may be a little while before we can welcome new members to our working parties. Thank you to those that have recently sent in their volunteer forms to join the ranks of our working members, we will welcome you to Blunsdon as soon as we are able.

Most of the work focused on getting our container set up which included the installation of the container lights and electrical sockets, at the request of the railway painting the outside green and various other small tasks. Work did progress on the locomotive with the removal of the springs that attach to the centre driving wheels. A preliminary visual inspection suggests they are good condition considering their age.

The removal of the lower piston and cover

Although we await the installation of a permanent electrical feed, we have a temporary connection to our newly installed consumer unit to give us both lighting and a ring main in the container. We have included RCD protected sockets for external tool use, sockets by the desk including USB charging points and sockets for the kindly donated microwave oven, fridge and kettle!

The stripping down also saw the right hand side piston and cover being removed. These have now been put into storage and will their condition will be assessed.

Removing some of the more stubborn bolts

The Society is happy to report that it was able to purchase some new components for the locomotive in the form of a Speedo drive, cut off indicator quadrant & part of the steam turbo generator. The components were from an enthusiast’s collection who offered them to the Society for an incredibly reasonable price.

Work in July was mostly focused around preparing for the boiler lift with some of the more troublesome boiler mounts being removed. The front boiler mounts proved especially resistant to being removed but after some head scratching a plan was devised and carried out that saw the mounts being separated.

 

Front end casing complete with lamps and disks

The main engineering highlight for this issue was the new front end casing which was successfully test fitted in July. The casing was originally built to be a surprise for our members at the cancelled AGM earlier in the year. The casing was built by the team at Leaky Finders who did another fantastic job for us.

Front end view of the casing

The two outside pieces are slightly bigger then they were originally built, we felt it was a sensible decision to make them bigger then we need to allow us trim them down during their final fitting and make a perfect joint to the rest of the casing. For the same reason none of the fitting holes were drilled, this meant we had to use some wooden props to display the pieces on the locomotive. The most complex part of the casing manufacture was the lamp irons which required machining to get the side profiles right before beginning to be bent into their into the final shape.

Boiler lift

CanPacs boiler lift inside Eastleigh works

The “Sponsor an inch or more” campaign that was masterminded by  Graham Muspratt was a huge success with the Society raising just under £2,000. The Society would like to thank Graham and all those who donated to the appeal. Getting the funding in place so quickly has made the planning for the boiler lift far simpler. At the time of publication a date has been agreed for the lift prior to the rearranged AGM although for health and safety reasons the Society will not be publishing the exact date.

With the relaxation of lockdown rules our volunteers have been hard at work preparing for the boiler lift. Our aim is to get all the remaining small boiler tubes cut and removed from the boiler before the day of the lift. The majority of the securing bolts have been removed with the remaining ones being left in for safety reasons. Our volunteers will remove all the final securing bolts the day before the lift.

Preparing the trailing truck for removal

The Society have been debating the possibility of removing both the trailing truck and front bogie whilst the crane is on site for the boiler lift. The agreed plan is to attempt to remove the trailing truck but we’ll leave the front bogie in place.  There are several reasons for this decision with the main factor being the Society is not in a position where we can make the locomotive immobile. The weight of the front end of the locomotive would require us to pack behind the bufferbeam in order to prevent the possibility GSN pivoting on her front drive axle. If GSN had a crank axle in place along side the rear drive wheel would have created a counter weight to balance the locomotive without either the bogie or trailing truck needing to be in place. The safest option we are taking is to remove the trailing truck and leave the bogie in place as this will allow us to push the locomotive back under cover once the lifts have been completed.

All the generous people who donated to the appeal will be entered into a free draw to win a number of prizes, including: a star prize of a Graham Farish N Gauge Merchant Navy Pacific locomotive, a years free membership to the GSNLR society, GSN merchandise and other prizes.

The raffle will be drawn at random at pivotal points during the boiler lift such as: The moment the first inch has been lifted, point of maximum lift, being clear of the chassis and then lowered to its new location. If you have donated and not contacted us to confirm your raffle entry with us please do at the earliest opportunity in order to ensure you don’t miss out.

Proxy Annual General Meeting 2020

The Coronavirus lockdown has caused an unprecedented amount of disruption to our way of life this year and led to us having to cancel our AGM which was scheduled earlier in the spring. The Society had hoped a physical AGM could still take place in 2020, unfortunately in the last few weeks it has become clear that it wouldn’t be possible.

The option that the trustees have decided to take going forward is to hold the Society and CIC (for shareholders) Annual General Meeting by proxy for this year with the expectation of being able to return to normal and hold a physical AGM in March 2021 subject to the relaxation of restrictions to enable us to host a safe event. The proxy AGM will take place on 1st October 2020 and will deal with the Society’s financial year that ended in February 2020 and the CIC financial year that ended in November 2019.

Included with the latest issue of the Packet members will find a booklet which contains all the financial statements for the last financial year, a report from the Society chairman, an agenda for the meeting and a proxy voting form. Please read the booklet carefully and return your proxy voting forms by Friday 25th September. Please note that votes arriving after this date will not be registered, so please send them in at your earliest convenience.

We are living in very uncertain and unusual times but its key that all the legal business of the project is completed correctly, on time and in a transparent manner. This does require a certain amount of flexibility which has been provided to us by the Government.

Fundraising Coach Trip Postponement

35011 at Southampton (Copyright P Rowlands)

Sadly due to the continuing Covid 19 situation in Lancashire & Yorkshire we have made the tough decision to postpone our joint

fundraising trip with the S&CR. With the current uncertainty and with our member’s welfare in mind we feel this is the best option. The new dates will be 21st-24th May 2021.

We intend to have the same itinerary as planned ( NRM York, North York’s Moors Railway, East Lancs Railway & Bolton & Embsay Railway) but this can’t be confirmed until the railways concerned release their 2021 timetables.

Those of you already booked will be contacted directly. Thank You for your understanding.
