Unfortunately Tornado was unable to attend her 10th birthday party in Darlington but it looks like Prince of Wales had a surprise waiting for the guests! Again, many thanks to all those who signed up to The Mikado Club to get No. 2007 on her wheels.

No. 2007 now has a full set of boiler cladding fitted, the pictures speak for themselves! (Photographs by David Elliott)
A start has been made with the trial fitting of the cladding on the frames and so far it appears to fit!

Excellent progress continues to be made with the process of wheeling and tyring at South Devon Railway (Engineering). These photos show the steps involved in preparing the wheel centres (now all fitted to their axles) for the tyres to be shrunk on. Assembling Tornado’s wheels used numerous contractors and multiple road miles so, for the Trust, having a ‘one stop shop’ that could do all the work has saved a lot of haulage and time.

Work continues at a great pace at South Devon Railway (Engineering). The tyre fitting is being done using the ex Swindon works tyre heating equipment. The quartering machine is a special form of horizontal borer which can bore crank pin holes or turn crank pins (if already fitted) from both sides of the wheelset at the same setting; provided the setting is not altered whilst swapping wheelsets, this ensures that the distance between the crank pins and the axle centres and the angle between the crank pins is consistent for all four wheelsets which is vital for smooth running of the finished locomotive.

Although the headline-grabbing wheelsets are away at South Devon Railway Engineering, work has continued at a fair pace at Darlington Locomotive Works, including the delivery of the spectacle windows and frames; the frames have been CNC machined from leaded gunmetal (bronze) castings by Durham Precision Engineering, the glazing retaining strips have been laser profiled from 6mm brass sheet by Holme Dodsworth of Newcastle. 20.5mm thick multiple laminated glazings with an anti-spall coating on the inside have been made to comply with current railway group standards by Romag at Consett. These components have been sponsored as part of our Dedicated Donation scheme – have you sponsored a component yet? If not, find out how to do so here.
Meanwhile Ian Matthews has been producing the fiendishly complicated compound curvature for the junction of the firebox cladding and that of the boiler barrel.

Although things may have been quiet at Darlington Locomotive Works recently, plenty of activity has been taking place at our supporting engineering firms and sub-contractors. Down in the West Country, South Devon Railway Engineering is making good progress assembling the wheelsets – remember, to support the wheeling of Prince of Wales you can join The Mikado Club but hurry, there are only a handful of places left! You can find full membership and benefit details here. All photos of wheels by Rob LeChevalier.
Meanwhile at Ian Howitt’s works, dozens of parts have been machined and assembly has started on the tender’s frames. All photos of tender parts by Ian Howitt.

In the last couple of weeks work has concentrated on fitting the bearings to the axles and preparing the axles and wheels for transport to the South Devon Railway for assembly. The following photos are by Mandy Grant:
On 14th March Allelys collected the driving and pony wheels for delivery to SDR(E) – photos by David Elliott:
In the last couple of weeks an awful lot has been going on at Darlington Locomotive Works. Three coupled axles have arrived and the leading coupled axle set up to press on its bearings. There has been some more progress on cladding and Daniela Filova has been producing manufacturing drawings on a regular basis. Orders have been placed for the cylinder cover patterns and castings, tender alternator pulley and roller bearing adjustment rings. The air pump which arrived in kit form reassembled and sent with its twin plus various ancillaries to Meiningen for overhaul. Ian Howitt collected tender hornblocks and liners and intends machining to start soon and the tender front dragbox is almost complete at North View Engineering Solutions prior to sending to Ian.
