The cylinders have been fitted to the frames of GER 789 marking a watershed with construction.
A further and more detailed engineering update will be published soon.

Tyseley Steam Locomotive Works continues to make progress with the assembly of GER 789’s frames.
The cylinder block halves have been bolted together and await installation upon delivery of additional bracketry in January 2021
The crank axle has been redesigned with the option for a forged or modular unit: other design factors will determine the final decision. During the Christmas/New Year holiday, CME Elliot Powick is designing the horn guides, braking system and suspension. During the first week of January 2021, orders will be placed for the three plain axle forgings plus the horn guide patterns and castings. In addition machining of all eight wheel castings is expected to proceed in January 2021.

Tyseley Steam Locomotive Works has commenced construction of the front buffer beam assembly.
Quotations for the machining of all wheel castings and tyre rings have been accepted. More engineering progress to be published soon.

In mid October the casings and were removed from storage and moved into the workshop, cleaned and painted with primer. GER 789’s frames were relocated to the workshop, setup straight and level on stands. Meanwhile the cylinder faces were cleaned up in readiness for coupling together with fitted bolts manufactured for this purpose. Buffer-beam angles and frame stay angles have been made. Meanwhile design work continues and quotes are being sought for the many factors that are required to provide for a rolling chassis. GER 789 will look very different by this time next year.

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.
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.
