All the frame stays we have are now permanently bolted in except for the front boiler support which shares bolt holes with the outside motion brackets. Ian Matthews has continued to fit the remaining components for the footplating and splashers with permanent bolting advancing towards the middle of the engine from the back. The front sections will remain temporarily assembled until the cylinders and outside motion brackets are fitted. All photos by David Elliott unless stated.

Buffers, chimney and whistle were added – Mandy Grant
The whistle has been made with movable stops for each of the three chambers and a temporary top with adjuster screws. When a suitable opportunity arises, we will use the chime whistle pad on Tornado to tune the whistle to the pre-war tone of C, F and A flat on 250 psi steam. The castings for the steam stand, its valve castings and the blower valve have now been delivered .
The pony truck and Cartazzi axles arrived near the end of September

The leading brake stay (which is the last of the large frame stays) is due for delivery imminently by North View Engineering Solutions in Darlington after which it will be permanently bolted in place.
The superheater header has also been ordered, modifying the Tornado pattern to allow for the two anti-vacuum valves on the P2 header. These pattern modifications are reversible such that in the future, castings for either loco can be produced.
The cab spectacle window frame castings have been cast at the South Lincs Foundry. All images by South Lincs Foundry.
These photos by Bob Hughes show Mick Robinson and Ian Matthews (re)assembling the cab after fitting the beading round the cab edge. In April 1935 the cut-out at the back of the cab side of No. 2001 was reduced to accommodate the fitting of bucket seats – this is the style adopted for No. 2007.
These photos by Bob Hughes show the ingenious process by which square sections of sandwiched metal are turned to the correct ‘almost’ half-round profile before being shaped and fixed to the cab.
Progress continues on many fronts, these images show a lot of effort being put into the frame stays, cab and sundry small parts. All photos by David Elliott.

Even when no large and impressive parts feature in our news, work continues at Darlington Locomotive Works to machine and fit many of those that have been cast or manufactured. In these photos by Bob Hughes Ian Matthews is seen machining part of the front drawbar spring block which was originally a casting and has been re-designed as a steel fabrication.

The kit of parts to make a temporary stay to fit where the cylinders will eventually go. This needed to keep the front frames straight to enable completion of the front footplating and also to act as a temporary support for the smokebox pending the cylinder block being fitted.
Assembly of the smokebox has proceeded well and the wheels are going to North View Engineering to have axle bores finished and keyways slotted. Photos by Bob Hughes and David Elliott.
