On the afternoon of Saturday 7th May, after our normal open day, we have a visit from Tanfield Railway Friends. 25 plus member had a tour of the unit and an update of our progress so far, also a glimpse of things to come.
It was great to have a group of like minded people coming to see what we are up to. We are both working together to preserve steam heritage, particularly in the North East of England.
If you are part of a group who would like a visit, please email firstname.lastname@example.org and we can book a time convenient for both parties.
We have had some good news, Daniela Filová, recently of A1/P2 trust, has set-up her own engineering company. It is in the same block of units, where we are, but just around the corner. This means we have a well equipped machine shop on our doorstep. Daniela Works, her company, has been commissioned to machine the two cylinder covers and the steam chest covers. Also to machine a full set of studs, for when we fit them.
Daniela set to work straight away to sort out a price for the work.
We were lucky enough to be invited to the 12th annual model railway exhibition held at the Youth Centre in Newton Ayclliffe. Arrange by the Rotary Club the show, which has missed the last two years, was well attended. We saw a lot of new faces who will hopefully visit our unit on one of our open days held on the 1st Saturday of the month 10am to 1pm.
We even had a visit from Sandra Haigh, the Mayor of Great Aycliffe.
Thanks to the invitation from Nigel Wright (one of our shareholders), Norman Raine recently attended a new working group who's shared objective is to develop technical and project management solutions in delivering locomotives fir for UK mainline running. The founder members are B17 Steam Locomotive Trust, Class G5 Steam Locomotive Company Ltd, General Steam Navigation Locomotive Restoration Society, P2 Steam Locomotive Company Ltd and Standard Steam Locomotive Company (72010 Hengist)
The inaugural meeting was held at CTL Seal Ltd, Sheffield, and focused on risk assessment and certification. It is anticipated that the meeting will be held every six months.
The order for the rear sandboxes has been placed, thanks to contributions to Superfriends.
We will have them early in the new year.
We held the companies AGM on Sunday 21st November at Shildon's Railway Institute. It was well attended, as always. The Railway Institute is full of history in the heart of the North East railway heritage.
There were many events happening across the North East this weekend to celebrate 196th years of the Stockton and Darlington Railway. We opened for an extra day on Sunday. I was great to see some new faces, those who couldn't attend on our Saturday open days. We will do the same again next year.
After a year without open days, we very quickly arrived at our second one. Here you can see Brian waiting to greet the many enthusiastic visitors who were waiting for us to open. If you look closely you will notice the new arrived and painted main brake shaft.
On the same day we also had a stand at the 'Little Big Meeting' held in Hackworth Park, Shildon. A mini celebration of mining and railways in the North East. We shared a tent with the Brusselton Incline Group and Friends of the Stockton and Darlington Railway. The event was well attended and the weather held off despite the forecast.
We held our first open day, for over a year, on Saturday 3rd July. We had a very busy day from the off. Thank you to everyone who attended. Many, who were existing supporters, eager to see the progress (and the quality of Mike's paintwork). We also had a number of people, who very new to the project, which is always nice.
Those who visited were lucky enough to see the pistons and just arrived crosshead bodies in the flesh!
The Class G5 Locomotive Company haven't let Coronavirius spoil their plans to acknowledge David Elliott's 70th Birthday on the 1st of March (St David's Day). Tim Taylor, G5 Company Secretary, presented a G5 cake, at the unit, to David in recognition of this milestone birthday and his involvement with the build,
David has been involved as the project's design engineer from the outset and his knowledge, skill and enthusiasm have been to the build's success.
Mike Wood, Chairman of the Class G5, said "It would have been fabulous to surprise David with a large gathering of supporters and volunteers at the unit in Shildon, but unfortunately lockdown scuppered those plans. We couldn't let this special birthday pass, so Tim stepped in to present the cake to David."
Following on from the success of Cash for Crossheads, allowing us to purchase the crossheads, we have launched the 'Put the brakes on' fund to enable us to buy the brake components. See Construction Funding page.
Please see 'Building Progress' for the latest update.
Due to the initial uptake of the 'Cash for Crossheads' fundraising scheme (go to the construction funding page, we are now in a position to place the order for the crossheads.
They are on a six month lead time. We still need to complete the fund so we can order the gudgeon pins, oil boxes, wedges and to machine the slots in the piston rods.
Our March Open Day and first of 2020 was well attended. We welcomed some regular visitors, some who hadn't been for a while and some who hadn't been before. Thank you to all who attended.
As the next goal of the project is a 'rolling chassis' (we have the main spring and spring hangers) the next parts we require are the Spring Links and Spring Hanger Links, so an order has been placed with Northview Engineering in Darlington for these.
Another Year, another AGM (and a cold one!) Hard to believe, but a year has passed since the last AGM. Thank you to all who attended, particularly those who travelled far to get here. It's great to get support for a North East locomotive from all corners of Britain.
The Friends' meeting was followed by the Shareholders' AGM. Mike Wood, our chairman, thanked those who attended, updated everyone of the progress over the last 12 months and expressed our deep gratitude to every person who has supported the project.
We have had a brilliant response to the piston plea (See Fund Raising page) and are now in the position to place the order for the pistons.
The order for forging blank and machining has been placed with Stephenson Engineering, who machined the coupling rods. Lead-time is about 16 week.
Thanks to generous contribution to the piston plea we have now placed an order for the piston rods. Delivery is expected within 6 weeks.
We are also in a position where we can order the pistons and have requested quotation on forging and machining of the pistons. If you would like to contribute to the piston plea, please go to the fundraising page and down load the application form.
Now that we have the main Axle Springs we need the components to hang them from the frame and take another step closer towards a rolling chassis, so we have ordered tye spring hangers (Drawing below)
This year's Conference took place on Saturday 29th June. Over 40 supporters of the project visited the unit on the afternoon for another of David Elliott's, project design engineer, fascinating technical presentation. The guest saw some of the new items just arrived in the unit (see build progress).
We then moved onto the Mecure Kings Hotel in Darlington for an evening meal and an informative and illuminatin presentation from Richard Barber, Trustee of the Armstrong Trust, on the life, social history and unfortunate demise of Darlington's North Road Locomotive Works.
Congratulations to Paul Flint who won the blind auction for the V2 worksplate on the evening. Thank you to David Barraclough for donating this.
Orders have been placed for the following: -
Front Sandboxes / Splashers
Main Axle Springs
Saturday 6th October saw the 11th Annual General Meeting of the Class G5 Locomotive Company Ltd. We were joined by over 40 Shareholders and Friends. Roger Womersley, one of the founder member of the company, stepped down from the role of Treasurer, which he has held since the start of the company in 2007. We thank him for efforts, enthusiasm and more importantly keeping the books straight. Steve Raine, one of the directors, was elected to take his place.
The AGM was followed by a fascinating film of Alan Tingate's reminiscences of his days as a fireman at Blaydon Shed.
On Sunday 12th August Aycliffe & District Bus Preservation Society ran a number of return trips from the Locomotion Museum, Shildon, to our unit. Thanks to all who visited.
Saturday 7th July saw the 3rd annual G5 Conference. At 3pm we had about 40 Shareholders and Friends at the unit for a superb technical presentation for David Elliott, our design engineer, on the progress and difficulties of the build. We then moved onto the Mercure King's Hotel in Darlington for an evening meal and a fascinating presentation from David Dunn, who has access to and is archiving the JW Armstrong collection (he currently has nears 450,000 photographs). David's presentation was of G5s in steam and being scrapped.
Lincoln Crankshaft have now completed the rough machining of the crankshaft. It will now have a slot cut out of between the webs to provide a test sample to comply with testing requirements. After this it will be ultrasonically tested for flaws in the forging and then the final machining will take place.
Many thanks to all the friends who have visited our open days throughout the year.
Hope to see you again next year.

PRESS RELEASE Thursday 4th May 2017
ORDER PLACED FOR THE LAST EXPENSIVE COMPONENT
THE CRANK AXLE ORDER HAS BEEN PLACED
Following on from a meeting on 19th April 2017 , which was attended by representatives of G5LC, Project Design Engineer David Elliott, Ricardo Rail, Mott MacDonald and Lincoln Crankshafts & Machine, the order has been placed to forge the crank axle.
This is a major step forward for the project as this is the last expensive component to be purchased, meaning the project is now around two-thirds complete. As crank axles are a safety critical item, this has taken around 12 months for all parties to be happy and clear about how the crank axle is to be produced.
David Elliott, Project Design Engineer commented: “The ordering of the crank axle for the new G5 locomotive represents a major step forward in the design engineering work required to permit main line running. The study work undertaken by Mott MacDonald has demonstrated that the minor improvements made to the design of the original G5 crank axle, and using a modern chrome molybdenum forging steel will produce a crank axle which complies with the modern national railway standards for axle design.
“This says a lot about the quality of the original design which dates from 1896!
“This milestone has been achieved with willing assistance from LC&M at Lincoln who have been contracted to forge and machine the new axle, and our assessment party, Ricardo Rail, who are monitoring and guiding us through the process of achieving design approval for eventual main line running.”
PRESS RELEASE Thursday 8th December 2016
MOTT MACDONALD APPOINTED FOR CRANK AXLE CALCULATIONS
Modern rail vehicles (and this includes new build steam locomotives) now require certification using the Common Safety Method for Risk Assessment (CSM-RA) - a pan European standard. There are 3 basic routes through CSM-RA:
1) Following national or international design standards
2) Using existing design where it has proved to be satisfactory and where the assumptions used in that design are known
3) Calculating and demonstrating that the components are strong enough for the job
The G5 class in common with many locomotives designed in the late 19th and early 20th century has its cylinders mounted between the frames. This necessitates having a crank axle to transmit the drive from the connecting rods to the wheels. By the time that today’s design standards were written, steam had been withdrawn and no modern rail vehicles have crank axles. Whilst the original design is believed to have worked satisfactorily, we do not have any of the calculations or assumptions used by the draughtsman in 1896! This precludes the use of the 2nd method.
We therefore need to undertake calculations and modelling to assess whether the existing crank axle design meets modern requirements. Given the complex combinations of forces that are experienced by crank axles, this would severely stretch the capacity of a piece of paper and a calculator!
Mott MacDonald Limited have considerable experience in rail vehicle analysis. In supporting the G5 project, they are now embarking on their second steam locomotive crank axle analysis project. Bob Harris Mott MacDonald Engineer commented:
Mott MacDonald use ANSYS Finite Element Software to do the work. The ANSYS software produces a very convincing picture of the stress in every part of the axle so it is vitally important that we define the correct inputs! The stress levels can then be used to work out how often, as well as where, the axle needs to be checked that it hasn’t started cracking, since they are critical to the safety of the G5.
In order to make this analysis as accurate as possible we need accurate figures for the weight of the components and as a starting point we have weighed the leading wheelset in order to accurately assess the weight of the crank axle wheelset. Have a look at the gallery to see pictures of this operation carried out by David Elliot.
Richard Maughan, CEO, The G5 Locomotive Company Limited commented:
“This is possibly one of our most significant milestones so far. It has stretched our financial commitment to the project, but Mott MacDonald are the renowned experts in crankshaft stress analysis and we will obtain the certification we require with their engagement. There is light at the end of the tunnel now for project completion”
The Crank Axle Degree Fund was launched with a target of 360 pledges of £100.00 – thus providing us with enough funds to purchase the crank axle; so far, we are over 50% of the way there.

November 5th went with a bang as usual and with it went out last open day of 2016; although don't forget that we can make special arrangements for shareholders to view the current stage of construction by contacting one of the team.
We will be back next year in March to start a new programme of Open Days.
We still have our limited edition O Gauge Ace trains G5 models for sale - just contact one of the team - they could make an exciting Christmas Present.
Hope to see you all again next year when we will have more exciting news of the progress in the con
New Year News (3rd Jan 2016)
Following on from the success of having the front wheelset returned from South Devon the Company have placed orders for:-
The machining and fitting of the motion bracket to the main frames.
The machining of the axle box housings
The casting of the Phosphor Bronze bearings for the axle boxes
The manufacture of the smokebox
The design drawings for the footplate along the sides of the frames
And the purchase of a reconditioned Wakefield Lubricator
All of these are currently funded through the sale of shares, very generous sponsorships and a significant contribution via G5 Superfriends
THE FRONT WHEELSET IS NOW IN THE UNIT AT SHILDON (14. 12. 15)
THE OTHER TWO DRIVING WHEELS AND PATTERN
HAVE BEEN RETURNED FROM BORO FOUNDRY
November 7th was our last open day for 2015, we expect to restart the open days at the beginning of March following the same pattern so the first Saturday in March should be it.
The front wheelset has not been returned yet although it is now complete, we are waiting for some machining to be completed on the two main driving wheels still a Borough foundry. When this is complete we have a contract for the collection of the front wheelset from South Devon and the two other driving wheels and wheel patterns from Boro Foundry. We expect all this to be back in the unit in Shildon some time in December 2015. The transport will be at the hauliers discretion in order to minimise costs.
Update on G5 Move
All of the components have been moved to the new unit except got the boiler which we expect to be in the new unit in the next few days. Have a look at the pictures to see the latest situation. 25.3.15
On the Move
From the 1st of February the G5 will be moving to new premises. The new unit is opposite the previous one at RRNE in Shildon.
This is the last phase in the construction of the locomotive and will see the frames turned over ready to accommodate the bogie and wheel assemblies. The new unit has much more space and will allow us to work on the construction and store all the assembled parts safely.
The cylinder blocks are now finally in position and the front buffer beam bolted into position. All the horn guides are now fully machined and bolted into position. The key ways have been machined in the leading driving wheels and we are awaiting transport to take the tyres and front wheels to Devon for assembly.
Follow links from building progress to see pictures of the cylinder blocks in position
Work is progressing with the fitting of the cylinders, the machining of the cylinder blocks is complete. The bolts need some final machining before the cylinder blocks and front horn blocks are fixed into position. The second hand right steam valve has been reconditioned and is now in full working order. The left hand steam valve which was bought new has been uprated with new stainless steel spindles to make them both the same specification.
Last Year's Events
The G5 Locomotion has received a lot of media attention lately from the local radio stations, The Northern Echo and the BBC. The latest coverage is can be viewed below:
Following the increasing media attention, our May open day was our most successful open day since the boiler launch.
From this open day we gained many new friends of the G5 and potential new investors visited Shildon to see the latest progress.
Someone who came to our 1st open day even uploaded their own video! Please Click Here
