Engineering Update - January 2017

Locomotive Frame Assembly

Work continues on the construction of The Unknown Warrior at number of locations.

Unfortunately, I have to start this report with some very un-welcome news. Chris Collins, one of the 2 Llangollen Railway Engineering engineers that is working on The Unknown Warrior has suffered a heart attack and has subsequently spent some time in hospital. I am sure everyone will join us in wishing Chris a speedy recovery and look forward to seeing him back at Llangollen as soon as possible.

Following on from the fitting of the Bogie at Tyseley on 4th February, work has continued on preparations to fit the Valve and Cylinder Liners.

The Unknown Warrior now a 4-6-0

Following the fitting of the bogie to The Unknown Warrior at Tyseley Locomotive Works in early February 2016 we are pleased to be able to publish these photos of The Unknown Warrior.in the yard at Tyseley.

Engineering update - December 2015

Locomotive Frame Assembly

Work continues on the construction of The Unknown Warrior at number of locations. The construction of a steam locomotive of any size is a complicated engineering task and the past few weeks have proved to be just that. While it may appear that not a lot is happening above the surface, in fact the 8 legged duck is paddling furiously although perhaps not all in the same direction!

2014 review - HELP US FINISH THE JOB

We have now reached a major turning point in the construction of 'The Unknown Warrior's' chassis, with a change in emphasis from manufacture to assembly. Much still needs to be done but with the last of the major castings now complete we are turning our attentions to the myriad of smaller parts which will be required.

New Bogie Wheel Cast

Less than a month from making the decision to manufacture a new wheelset for the locomotives bogie, rather than wait any longer for the possibility of a set from an 8F in Turkey, the first Wheel Centre has been cast. 

The 3D CAD data was supplied to Premier Patterns by the project's CAD Designer, Kevin West and the pattern cut in a polyurethene foam.

Engineering Update - July 2014

Locomotive Frame Assembly

Following the wheeling of the chassis at Tyseley Locomotive Works in late June the chassis was only display at the Tyseley Locomotive Works Open Weekend on 5th & 6th July, before moving back to Llangollen on Friday 11th July.

That one small sentence does not explain the effort and logistics involved to move the chassis the 80 miles between to two sites.

Full set of Cylinders for 'The Unknown Warrior'

'The Unknown Warrior' now has all three cylinders following casting of the second Outside Cylinder at Coupe Foundry, Preston, on 3rd July.

Engineering Update May/June 2014

'The Unknown Warrior' is Wheeled.

We realise that building a complex locomotive like the Patriot was never always going to be a straight forward exercise. The last few weeks have been interesting and challenging to say the least. From the outside it must have looked as though nothing was happening, but I can assure you it was a bit like a duck swimming across the lake, all calm above water, but below the legs are working furiously in all directions at the same time!

Engineering Update - April 2014

Work continues at Tyseley Locomotive Works on preparing to fit the axleboxes into the main frame. All the Horn Guides have been polished to remove machining marks and the corners radii added by hand. All this has been completed to the usual high standard expected from Tyseley.
The Axleboxes have had the brasses pressed in and the journals have been machined to the size of the axle. The bronze wearing faces are now being machined to the sizes determined from the frame assy.
