The Holden F5 Locomotive Trust is making preparations to erect the frames and create the ‘rolling chassis’ of its Great Eastern Railway 2-4-2T No. 789, with the completed cylinder castings delivered to Tyseley Locomotive Works, and design work well in hand on the rest of the ‘bottom half’.
The CAD (Computer Aided Design) patterns for the driving wheels have now been finished and will be sent out for quotations in the coming weeks, along with those for the axles and axleboxes. The modified  axlebox horn guides and their infill plates have also been designed.
The last remaining large part to be produced for the frames will be the motion bracket – but because the drawings for the Stephenson valve gear have not survived, a new design will have to be produced from scratch and modelled to ensure that it fits together.
Project Manager Elliott Powick of Stafford Road Design Ltd said: “Once this is finalised Tyseley can put together a plan and costing for the frame erection, so the kit of parts that the group already have can be turned into something more than a large Meccano set.”
The frame plates were cut in 2012 and the cylinders cast in 2014, while the Trust has also produced the ‘star stay’ (a star-shaped frame stretcher beneath the cab), the smokebox and door, chimney, bunker and bufferbeams.
For more details or to make a donation (payable to Holden F5 Steam Locomotive Trust) write to 49 Beech Avenue, Halstead, Essex CO9 2TT
The group’s sales stand will be in attendance at The North Norfolk Railway on 3rd September 2016 and the Festival of British Railway Modelling, held at Doncaster Exhibition Centre on February 11/12 2017. For additional information please click on “Meet the team”

Wrenford Thatcher GER 789 Commission.

Wrenford Thatcher is one of Britain’s most successful railway artists, currently creating stunning artworks depicting accurate records in railway history.

Wrenford Thatcher was born in 1944 in Hertford and led a happy childhood on the footplate, around both grandfathers who were engine drivers,  working on the former GER, LNER and finally for BR. From the war years onwards, Wrenford lived in Hatfield and spent his spare time at the line side sketching trains.

He attended St Alban’s County Grammar School where he excelled in sciences and the arts, winning a number of awards for his artworks. He attended London University and studied Mathematics and Physics where he achieved a PhD in Physics. Wrenford became a teacher of Electronics and Astronomy at various Universities, entailing extensive travelling in America and Europe.

Throughout these journeys, paintings flowed whenever time permitted. Two subjects dominated his interest; the stunning scenery of the west coast of Scotland and most importantly, steam locomotive and railway scenes, no doubt stemming from his grandfathers.

His railway paintings are always met with great enthusiasm and has perfected a style that encompasses precision, accuracy and attention to detail, tackling the complexity of perspective. Each painting faithfully represents an historical account of a golden era, reflecting Wrenford’s unquestionable passion for railway engineering.

GER 789 at Stratford station low level.

Although it is generally not recommended that paintings are hung in direct sunlight Wrenford Thatcher’s paintings will withstand it more than most because he uses natural pigments such as raw umber, yellow ochre etc which will not fade. Only red buffer beams are at risk as the use of arsenic red is no longer permitted! The painting is spectacular in sunlight-the shaft of light on the locomotive makes the blue livery stand out from the grey surroundings. This is a technique which Wrenford Thatcher has copied deliberately from the old grand masters such as Rembrant through to Canaletto who knew all about this. The technique was lost by the impressionists and has never resurfaced.

A limited edition of signed and numbered, high-quality prints of Wrenford Thatcher’s GER 789 will be available for purchase in the near future. For more information please contact info@holdenf5.co.uk.

Although the cylinders have been manufactured, the C.A.D. model is vital to ensure that all componemts align correctly before the build commences. As shown above, the cylinder block consists of two halves that sit between the frames. Refer to the illustation below.

6100 was renumbered 46100 by British Railways after nationalisation in 1948. In 1950 46100 was rebuilt. It was withdrawn in October 1962. It was bought by Billy Butlin for Cosmetic Restoration and displayed at the Skegness Holiday Camp. It moved to Bressingham Steam Museum in Norfolk in 1971, and bought from Butlin’s in 1989. It was sold in 2009 to the newly formed Royal Scot Locomotive & General Trust, and after an extensive refurbishment,      re entered service in 2015.

Cylinder Re-finishing

Following an initial inspection at Harco Engineering, it was decided to go ahead and attempt the cleaning up operation following the welding of the port faces. One of the main problems with welding process is the amount of heat required to achieve this, the downside being that a small amount of distortion has been accrued whilst doing so. To this end the two mating faces were skimmed square and the ports then re-machined from their new datums.

 One of the cylinders pre-machining

This picture shows one of the cylinders pre-machining.

Thankfully this operation has been a success and the mating faces cleaned up following a very small clean up and all the port faces machined well with good mating surfaces achieved.

Here we see one of the completed re-machined cylinders ready for the next stage.

Both cylinders cleaned up and awaiting the final stage of machining

Both cylinders all cleaned up awaiting the final stage of machining.

The second and final stage is to correct any ovality in the bores. Obviously, we only want to remove the minimum amount of material but the bores will be slightly offset bored to correct any mismatch due to the new skimmed mating surfaces, this will then bring everything back into true alignment for cylinder centres.

Chassis Build

Now that we know the cylinders are fit for purpose we can continue with the next stage in the build,  erecting the chassis.

I had a meeting at Tyseley at the end of April to discuss the way forward and plotting a course to make a start on frame erection. It was agreed that the best plan of action is to get all parts required ready before they make a start and to this end I’m currently reviewing the CAD model to ensure all parts are present and correct. One of the larger missing parts is the motion bracket, this is currently in the process of being modelled for poly pattern manufacture and hopefully, will be off for casting and subsequent machining in May.

Once we have all the parts either manufactured or on their way, Tyseley can give us a quotation for the build and we can really push on with the build in earnest.
