In the workshop

257 Squadron's overhaul continues on all fronts, however delays to the boiler are inevitably pushing back the completion date. The boiler is being overhauled at A D Engineering in Stockton under the supervision of the Boiler Inspector, who has requested significant additional work, notably replacement of the upper section of the inner backhead which must be done before other work on the inner crown. Several months more work is needed before its hydraulic and steam tests. This will result in a better boiler for the long term, at the price of a delayed return to service and significant extra cost.

The heritage railway industry needs to take a holistic view of how it operates steam locos, e.g. water treatment regimes, in order to extend the life of steam locos and minimise overhaul costs. Around the country there are many locos out of service awaiting major boiler work, few workshops capable of doing such work, and even fewer owning groups with the cash to pay for it.

Eddystone at Herston

The new tender to run with 34072 257 Squadron approaches completion. The tank sides have been cleaned and primed, new electric lights have been fitted, and the vacuum tanks are being piped up. There was a manufacturing fault in the springs which have been removed for correction.

The top pivot of the main brake hangers are being re-drilled before they are re-bushed. That needs quite a meaty drill; the smoke in the photo comes from the copious lubrication being applied.

The water gauge castings are ready to fit to the fireman's side of the tender.

Ian Dunford has recently joined SLL's staff. Ian comes from Poole and has a grandson whose favorite loco is Eddystone - the workshop staff will be seeing a lot of that loco in the next couple of years!

The smokebox has been refitted to the frames, hopefully for the final time, and front cowl is being fabricated.

80104 is back in regular service on Swanage Railway after its protracted boiler repairs. Currently facing south, it's seen arriving at Swanage on 12th May.

34053 Sir Keith Park

Eddystone at Herston

34053 Sir Keith Park remains in regular service on Severn Valley Railway. It's seen here on a Footplate Experience trip run for a group of SLL supporters on 19th May. SKP has been joined by a second Bulleid on the line; 34027 Taw Valley re-entered service in May.



The Embsay loco team have been busy with the paint brushes, and Norman is currently in NCB livery, reflecting its years working at collieries. It's seen here on 20th May outside the Embsay workshop after a boiler washout.

2015 AGM and Shareholders Drive & Fire days

The AGM will be held at the Mowlem building in the centre of Swanage on Saturday 24th October. Formal notice will be given nearer the time. A steady stream of shareholders have already requested places on the Drive & Fire days with Manston and we have asked Swanage Railway if they can add a third day, Wednesday 21st October, to meet demand though we may not be able to accommodate everyone. Priority is given to new shareholders, active volunteers and those able to be flexible with the date and times they request.

February 2015

In the workshop

Work continues on 34072 257 Squadron and its new tender. The valve gear and motion are gradually coming together. The sanding gear has been installed, likewise the main brake hangers. New main springs were bought from Owens Springs Ltd. and have now been attached to the axle boxes. The smokebox has been on and off the frames twice, and welding is now being completed. It won't be installed on the loco until the boiler is in place, which is still some weeks away.

257 Squadron   257 Squadron

Each main spring weighs around 100 kg. They were lifted by the forklift and lowered between the frames close to the rear axle and man-handled into place.

At Herston the track stands on the concrete floor, with no pits. Plywood is laid across the sleepers to make a smooth surface - important as much work is done from a crouched position.

257 Squadron   257 Squadron

Each spring is raised about a foot to attach to a D-link which hangs from the axle box. The D-link can swing laterally on the axle box, allowing movement between the wheels and the loco.

The springs for the leading axle are tricky as the oil bath obstructs access. The spring is hoisted above the rear hanger, then pulled forward to align with the D-link.

The tender approaches completion. Lamp brackets, ladders and conduit are being fitted, and the external steelwork needs preparation prior to painting. Someone needs to get inside the tank and clear the floor of welding debris. A nice job for a thin person!

257 Squadron   257 Squadron

Four vacuum reservoirs are mounted on top of the tender. They sit on a wooden rack.

The tender cab of a Bulleid has all mod-cons; space of the fire irons, a door to the coal, and cupboards for the crew.

257 Squadron   257 Squadron

The ladders and conduits have been fitted to the rear of the tender.

Bulleid pacifics have electric route lights made from brass. Several more are being made to complete the new tender.

The RH motion partly assembled. Note the radius rod running forward, attached to the combination lever, and the valve plunger which carries the drive through the wall of the oil bath.

257 Squadron   257 Squadron

257 Squadron's coupling rods had not been cleaned since the loco was withdrawn in 2001. Ray, Simon, Claire, Alex and Bailey got to work and they're now ready to fit.

The inside connecting rod needs to be fitted before the boiler goes on. The inside big-end has a split bearing as it has to fit the crank on the middle driving axle.

There is a new Picasa gallery showing 2015 restoration work. Not many photos so far, but the number will grow rapidly as 34072 comes together this year.

Would you like to help build a loco?

There's a constant stream of jobs suitable for volunteers with all levels of skill. If you are a practical kind of person, happy to work with others, we'll give you a warm welcome and keep you busy. The pay's lousy (i.e. none!) but the tea's good, and there's a real pleasure in seeing a 100-ton locomotive come together, and knowing you built part of it.

Interested? Drop in to Herston works and ask for Willie or Bob. Or call Nick on 01395 519335.

There's more about volunteering here.

Would you like to join our staff?

We're looking for a skilled Machinist/Fitter to join our paid team, focusing on mainly on the machine shop. This could be a full or part time position. If you're an experienced user of lathes, milling machines, etc, please send your CV to Willie Bath (email:

34028 Eddystone

Eddystone at Herston

We were hoping to report that Eddystone was on the move, and that plans for its boiler lift, de-greasing, etc, were in hand, but for the moment we're somewhat stuck, and the loco is likewise stuck, minus connecting rods, in a siding near Swanage. We're looking for suitable site to release the boiler, send it off for repairs, and send the frames for water-blasting, so that we can hit the ground running when 257 Squadron's overhaul is complete.

80104 - returning to service


80104's boiler returned to Swanage after extensive repairs back in October, but it's taken a while to put it back into working order. Meanwhile a lot of other repairs and improvements have been made to the loco, and it needs only minor attention to re-enter service with a new 7 year ticket. It made a succesful run on Swanage Railway on Friday 20th February, and should be back in service from 1st March.

A cloudy forecast for Sidmouth

Given the choice between two-year 250,000 overhauls and a five-year million pound restoration project, it's not hard to see why we'll be focusing on the overhauls of 257 Squadron, Eddystone and Manston for the next few years. 80104 has a new seven year boiler ticket, but its axle boxes will need work before too long.

So where does that leave Sidmouth? We don't have a good answer to that, though the subject often gets raised. "Blue sky" suggestions include restoring it to the point of a rolling chassis in the hope that might attract a sponsor. Or we might restore the boiler and use it initially as spare for our other Bulleids, cutting the length of overhauls, as was done in steam days. It was even suggested that we did a cosmetic overhaul and displayed it in the town of Sidmouth. (The webmaster's back garden was mentioned, but Mrs T. was less than enthusiastic!)

We're not going to sell it for scrap, sell off parts, or sell it to anyone without the wherewithal to restore it. However if there's a heritage railway, restoration group, or an individual with a viable plan we'd like to meet them. We don't know what that plan would be, though we'd certainly like to see 34010 running again irrespective of ownership.

Sidmouth's frames are stored on a flat wagon near Norden.

Its boiler is at Bridgnorth, where it was used as a template for the cladding of Taw Valley.

Social media

Love it or hate it, it's part of today's world, and much of SLL's public attention comes through our Facebook and Twitter accounts. We recently passed the level of 1000 "likes" on Facebook, and we have even more followers on Twitter. That means that when we post a photo on Facebook it pops up in at least 1000 people's PC, tablet or smart-phone. That compares with 60 - 70 views of the website per day. The photos in our "2014 Restoration" Picasa gallery have each been viewed around 600 times. That's a lot, but a Facebook photo of 257 Squadron being re-wheeled was viewed by over 3500 people in the course of a few days.

Does than mean that a website is now obsolete? No, but it should play to its strengths as the long-term repository of information and anecdotes, explaining the company's mission and work in depth. Expect to see website news updates every two to three months in future, plus some new reference pages.

January 2015

In the workshop

Work proceeds on 257 Squadron five days a week, though the untrained eye would not notice much change from day to day. (Next time perhaps we should install a time-lapse camera to record every small step.) However, now and then big changes happen; in November the loco was rewheeled and on 5th December the tender tank was mated with its frames.

The tank was fabricated in Stockton and arrived on a semi-lowloader. It needed to be lifted from the truck, moved to the back of the workshop where the frames were waiting, and lifted into place. This was done using a HIAB lorry from Poole Boat Transport Ltd which has a built-in crane capable of lifting the tank weighing around seven tons.

257 Squadron   257 Squadron

The tender tank is lifted by the HIAB truck and lowered on to its own platform. The sump and flange on the tank mean trestles are needed.

The HIAB truck moved gently to the back of the workshop and lifted the tank into position on the frames.

First the tank was lifted by the HIAB and positioned on the rear of the truck using the large trestles which had been used construct the frames. It's all very well to add together the heights of the truck's deck, the trestles and the tank above the trestles, and compare that with the height of the roller doors to the building; that indicated there was approximately three inches clearance. However as the truck edged towards the doorway, and in the absence of any obvious plan B, there was a flicker of anxiety amongst the bystanders. Oh ye of little faith! It passed through the door with three inches to spare!

The final step was to unfurl the HIAB crane again (it's rather like a "transformer"), and lift the tank on to the frames, and - what d'you know - it sat on the frames smoothly, and aligned to within less than an eighth. Job done!

257 Squadron   257 Squadron

En route the tender tank passed the loco. The smokebox now has its characteristic Bulleid front plate.

Meanwhile work continues in the machine shop. Ron Neal machines a piston rod, with crosshead attached. The final pass will be with a grinding attachment.

The final big step is the return of the boiler. Work is continuing at A.D.Engineering Ltd. (see below) but it's still a couple of months away as new thermic siphons are needed, the existing ones being beyond economic repair. They have been bought from SDR Engineering Ltd., where they were "off the shelf" (which is quite a thought in itself) though they will need further machining and welding. This adds at least 12,000 to the cost of the boiler work, but will be quicker to complete. and in the knowledge that siphons have been a weak spot on other preserved Bulleids it seems money well spent.

Eddystone at GDSF

The thermic siphons were removed from the firebox and tested for corrosion and thickness. The decision was to buy new siphons. Note the hole visible in one section.

34028 Eddystone

Not much to report on Eddystone. It remains in a siding at Herston, and there's no news yet about when and where it will go to for boiler lift, cleaning, etc.


Norman has been hard at work at Embsay for several years, though this year it's seen less service than usual. In August it was stopped while its boiler test was arranged, and just before Christmas it was stopped with a leaking tube. It may also need some work on the bottom end before too long, and attention to the crown stays.

2015 plans

2015 promises to be a busy and interesting year for Southern Locomotives. We will be working flat out on 34072 257 Squadron; the target is to have it "complete" in August, and running on Swanage Railway in October. We expect the boiler to return, hydraulically tested, towards the end of March, and on the frames by the end of April, giving us three months to finish the lagging and cladding, final fitting, painting and then steam testing. Doubtless some further attention will be needed before it can move from the works to the railway. A further round of testing and fettling will ensue before it can enter service.

September 2015 marks the 75th anniversary of the Battle of Britain, and as owners of three Battle of Britain class locos we hope to take a full part in railway based commemorations. Quite what form those celebrations isn't determined and depends, among other things, on the completion of 257 Squadron.

257 Squadron   257 Squadron

Among the exhibits at the RAF Museum in Hendon is the remains of a crashed Hurricane from 257 Squadron.

There's also a plaque with the 257 Squadron crest, adjacent to the large statue of Sir Keith Park which was mounted on the fourth plinth in Trafalgar Square prior to the permanent statue in Waterloo Place.

Meanwhile readers may wish to pencil in the Swanage Railway Autumn Steam Gala, 16-18th October. We're minded to hold our AGM a week later on Saturday 24th October, and to arrange our shareholders annual Driving & Firing on the preceding days. Nothing's fixed yet, so please "watch this space".


The webmaster visited A.D.Engineering in Stockton-on-Tees in November to see the progress on 34072's boiler. Adam Dalgleish has built a team of experienced boilersmiths and welders, plus apprentices, and can call upon other specialist skills in the north-east. A lot of work has already been completed on our boiler, but more is required. The thermic siphons are badly corroded and will need replacement and sections of plate in the crown of the boiler need to be replaced. We're looking at completion in March 2015, all being well. The company has also built the new tank for 34072's tender, and this was delivered in early December.

When this website was first launched in September 2009 the webmaster stated a policy of Kaizen, which means "good change" in Japanese, and was used by that country's car industry to improve its products. It has since become a widely used slogan, usually translated as "continuous improvement". We asked for your comments on the content, both stylistic and factual, right down to split infinitives, up with which we will not put!

So Null Points to the webmaster for the line "Eddystone's overall will cost more than 200,000" in the last news update. It was there for several days before it was noticed, or maybe readers were too polite to point out the gaff.

So we got away with that one, but do please let us know if you spot a slip, however minor.

Eddystone is currently in store at the Herston sidings. It's expected to move to Stockton for boiler lift and cleaning in a few weeks.

Eddystone appeal

Thank you to all of those who have submitted share applications to support Eddystone's overhaul. So far we are well into four figures....though that leaves quite a way to go given that the total cost of the overhaul is likely to be in excess of 200,000.

The webmaster bought another share and claimed his print of Eddystone which is now gracing the wall of SLL's Global Digital Communications Hub (aka the spare bedroom).

In the workshop

5th November saw a big step forward in the overhaul of 257 Squadron; the loco was rewheeled, and the new tender frames were also wheeled. The cab body is complete and most of the smokebox is in place. The new tender tank is largely complete and will travel south to be fitted in the next few weeks.

The rear set of wheels are in place. The loco is now fully wheeled, including the front bogie and rear truck.

Photos showing the rewheeling of 34072 can be seen here.

One of a steam loco's most crucial components are the bearings of the driving axles. The are plain bearings lined with white metal, a group of alloys containing of tin, antimony, copper and lead. In the last years of UK steam a number of locos used roller bearings (most notably the LNER A1's) but white metal was the norm, and was often the Achilles Heel. Did O V S Bulleid consider roller bearings for his pacifics? If he did wartime constraints probably ruled them out.

In the video Ron Neal pours white metal to make a smaller bearing, part of the brake linkage.

2014 Driving & Firing, and Annual General Meeting

On Saturday 27th September our Annual General Meeting was held at the Engine House, Highley, on the SVR. Around 30 shareholders attended the meeting, the formalities passing without incident. Richard Moffatt has rejoined the board of directors. Richard has been involved with SLL for many years. He's also a regular at the K&ESR, and part owner of a GWR 2-8-0T, though that should not be held against him!

During the three preceding days more than 20 shareholders enjoyed driving and firing trips with Sir Keith Park. The SVR had provided a serious load - seven bogie coaches - for SKP to haul, giving our crews plenty to think about, and a chance to open the throttle on the climb up to Bewdley Tunnel.

80104's boiler returned to Swanage on 23rd October and was immediately re-united with the loco in Swanage station yard. A new ashpan was also attached and the loco should return to service in time to work the Santa's. It's expected to have a seven year boiler ticket, taking it through to 2021, though the main axle boxes will also need overhaul; that work will be scheduled in the near future, depending on service requirements and availability of lifting facilities.
