GER 789’s frames positioned for assembly. Elliot Powick.
GER 789’s frames were recently positioned inside Tyseley’s workshop signifying the commencement of the build. Meanwhile castings have been removed from storage, cleaned and painted ahead of fixing to the frames.

Diamond stay and tank supports. Elliot Powick.
The first task will be to rivet the star (diamond) stay to the rear of the frames and to remove the temporary stretcher that was installed to facilitate transport to Tyseley earlier this year. In the coming weeks the machined cylinder halves will be prepared for additional machining and bolted together prior to being fixed to the frames.
The Trust has received a legacy that is sufficient to provide the rolling chassis however funding continues as a contingency hence we welcome your interest greatly. To survey how you can assist please click on “How you can help.”
The Holden F5 Steam Trust has received written confirmation of a legacy that will fund the completion of GER 789’s rolling chassis.
The existing engineering plan is to proceed as scheduled ie The Tyseley Steam Locomotive Works will continue with the build of the frames over the ensuing four months. CME Elliot Powick is currently collating costings for all components necessary to provide the rolling chassis. Meanwhile design detail continues and a further and more comprehensive engineering report will be published soon.
The boiler
It is anticipated that a residue of the legacy will part fund the boiler hence fundraising continues.
The Board of Trustees,
The Holden F5 Steam Locomotive Trust.
Tyseley Steam Locomotive Works and The Holden F5 Steam Locomotive Trust has reached an agreement that facilitates enabling works to commence ahead of the assembly of GER 789’s frames. The construction of GER 789’s frames is expected to get underway within the next few weeks and take 4 months to complete.
The front buffer beam stiffener, gussets and other brackets required for the erection of the frames have been manufactured.
Regular engineering updates will be posted during the course of the build.

Meanwhile all eight wheel castings have been delivered to Tyseley ahead of machining.

The Board of Trustees via Elliot Powick (CME) is able to report that Tyseley Steam Locomotive Works has quoted and provided a work schedule for the assembly of GER 789’s frames. As you will see below the amount of work to be undertaken by Tyseley is to say the least, “comprehensive” and with the exception of the horn-guides and radial trucks will provide frames to accommodate wheel-sets.
Tyseley has started preliminary work with the fabrication of gussets and the stretcher that is riveted behind the front buffer beam. The cylinder block and diamond stay are to be removed from storage and prepared for additional machining. Construction of the frames is scheduled to commence at the latter part of September 2020.
The predicted timescale from start of work to completion is approximately 4 months. Tyseley is to provide engineering updates plus images of progress throughout the build.

A major engineering update and an official press release will be published soon. Meanwhile the Board of Trustees extends its thanks to you all for your continued patience.
Morgan UK LTD of Tyseley is fabricating the brackets required for GER 789’s frames assembly. Other components necessary to complete the frames such as horn guides are at the design stage with patterns pending.
Just Giving
The Holden F5 Steam Locomotive Trust extends its grateful thanks to all those individuals whom have donated via Just Giving. Due to the majority of the events we had planned to attend in 2020 having been cancelled due to the pandemic, Just Giving has been proved itself to be an extremely valuable fundraising aid. Alternative methods of donating to GER 789 are available by clicking on “How you can help.”
Thank you for your continued interest and support,
The Holden F5 Steam Locomotive Trust.
Despite the near lockdown of the greater majority of UK engineering facilities, the Trust via the much valued services of our CME Elliot Powick has been successful in obtaining the first of several requested quotes for plasma cutting of the steel that will be required for the main frames bracketry. This process is proving to be a protracted affair due to the effects that Covid 19 is having on UK engineering however we will publish a more detailed engineering report as soon as we are in the position to do so.
Meanwhile we thank all our members and donors alike for your collective patience and understanding during these difficult times,
The Board of The Holden F5 Steam Locomotive Trust.
Radial trucks.
During the early years of “The Holden F5 Steam Locomotive Trust,” our then CME Graham Rowland invested a vast amount of his personal time locating and researching many archives in his quest to amass a full collection of F5 drawings. Despite an exhaustive and very time consuming mission it became apparent that two key sets of drawings were unavailable; they simply did not exist namely the Stephenson’s valve gear and the radial trucks. Nevertheless Grahams persistence in locating what drawings survived enabled the construction of GER 789 (F5 67218) to proceed.
Eventually under Graham Rowlands’ lead the peripheral frame comprising of machined buffer beams and valences, smokebox, chimney, rail-guides, bunker and frame plates were manufactured.
Work commitments eventually deprived Graham of Holden time hence Kevin West agreed to further progress GER 789 resulting in our introduction to polymer patterns that greatly reduced the cost of patternmaking. Soon we had in our possession a machined cylinder block, machined tank supports and the substantial diamond stay that sits beneath the footplate.
Kevin West was to leave due to his commitment to another new-build project to be replaced by our current CME Elliot Powick.
Elliot Powick set to work initially cross referencing work undertaken by Graham Rowland and Kevin West prior to further developing ongoing 3d CAD models. Elliot’s’ work to date includes designing the Stephenson’s valve gear, plotting the numerous holes on he frame plates that culminated in their CNC machining, identified the correct design of motion bracket as the original piece tendered four different options. Recently, Elliot oversaw the design and casting of all eight wheels and further progressed the design of the crank axle.
As mentioned above the drawings for the radial trucks are deemed not to exist hence Elliot has designed 3d CAD models from information obtained from factors associated with his research and development of GER 789’s build.

The two radial trucks represent the final two major castings that will enable GER 789’s assembled frames to accommodate the leading and trailing wheelsets.
The cost of the polymer patterns and castings is quoted as £10,000.00 and we are currently fund raising this amount of monies. To survey how you can offer your kind assistance please click on “Sponsor a Part”
With your valued assistance GER 789 will be advancing towards a steaming date.
