The additional work on the frames of Flying Scotsman is progressing according to plan. We are still working towards a 2015 completion date for the project to bring this iconic locomotive, the sole survivor of its class, back to Britain’s tracks.
Frames at Riley & Son
It was decided that new frame sections were required when a trial fitting of the cylinders to the frames earlier this year showed how badly out of alignment and elongated the mounting holes were. Although we always anticipated that some remedial work would be needed in this area, the amount of welding that would have been required would have necessitated a lot of heat to be applied in adjacent areas, with potential deformation of the frame plates.

The new frame plates, which are 12ft in length and 1 1/8 inches thick, have now been manufactured at Arthur Stephenson’s Engineers Ltd, Greater Manchester. They will be trial assembled there with the smokebox saddle and other components that will assist their eventual fitting to the locomotive.
New plate frame sections completed
The work on the middle cylinder is now fully complete and the next stage in the project is the machining of the smokebox saddle and the making of a framework jig. Once this is complete, the trial assembly will take place and then the fitting of the new frame plates will commence at Riley & Son (E) Ltd.

Last week (w/c 11 August) marked a milestone in the Flying Scotsman restoration project with the completion of the major works to the cylinders.
Although there are some smaller elements to finish still, the fitting of the new cylinder liners by the team at Riley & Son (E) Ltd in Bury last week means that the remedial work on the frames is now the major task in hand.

The team at Riley & Son (E) Bury Ltd is still working hard on Flying Scotsman's cylinders and the work on all three cylinder blocks including the fitting of the new valve and cylinder liners will be complete in the next few weeks.
Some remediation work on the frames is needed to ensure the finished cylinders can be fitted in the correct location.
Work is also being carried out on the buffer beam castings, the slide bar and motion brackets to make sure everything is correctly aligned.
We still anticipate a return to steam next year for this iconic locomotive, the sole survivor of the A3 class.

2. Middle cylinder block. The mounting holes have been re-drilled and the valve liners have been inserted. This work will be finished in the next few weeks:
3. One of the slide bars has new packing pieces machined, checked against original engineering drawings:
4. New buffer beam components are manufactured from new plate:
5. Cracks on the buffer beam castings have been marked up ready for remedial work:

Work is progressing well on the project to bring Flying Scotsman back to steam. Here are some pics taken of the work on the cylinders being undertaken at Riley & Son (E) Ltd, Bury.
