Engineering updates

Project Update - March 2013

The LMS-Patriot Project, is pleased to announce that Heritage Painting has been chosen to paint the new ‘Patriot’ 4-6-0 locomotive - 'The Unknown Warrior'.

Heritage Painting, the specialised railway vehicle painting service has already repainted high profile locomotives including ‘Mallard’, ‘Flying Scotsman’, ‘Dwight D. Eisenhower’ and Black 5 number 45407.

Engineering update - March 2013

Stretcher number 5 - the final stretcher that is needed for 'The Unknown Warrior' was delivered to the Llangollen Railway Works during March, after being cast at the Boro Foundry. The Lye foundry near Stourbridge has previously cast the other four frame stretchers, bogie centre pin, and driving wheels for 'The Unknown Warrior'.

The bogie frame plates were cut during March at Morgan UK Ltd. Fabrications of Tyseley and were delivered to Tyseley Loco Works where assembly of the bogie will take place.

Engineering update - January 2013

Following on from the assembly of the three 6' 9" driving wheelsets for 'The Unknown Warrior' at South Devon Railway Engineering last year, quartering and fitting of the crank pins has now taken place. There are four different designs of crank pin that are needed for 'The Unknown Warrior'. The quartering of the crankpins ensures the correct alignment of the crank pins in relation to the cranks and axles. The lining up for this job took nearly two hours per crank pin, while the boring process took around a day to complete for each hole, with each cut taking around 15 minutes. About 30 cuts were required, depending on the final size of hole needed for each crank pin. South Devon Railway Engineering is believed to be the only railway engineering workshop that can do traditional crank pin quartering.

Spring Hangers and Cross Stay Blanks Made for 'The Unknown Warrior'

Twelve spring hangers have been made for 'The Unknown Warrior' with assistance from Project Director Neil Kinsey. The spring hangers were machined at Fastlok Engineering Ltd. in Nottingham and have now been taken to the Llangollen Railway Works to enable the rolling chassis to be assembled.

New Driving Wheel Springs Made for 'The Unknown Warrior'

The first new items for 'The Unknown Warrior' to be completed during 2012 were six driving wheel springs. These were made from new by Owen Springs of Rotherham. They were assembeld with 14 separate leaves. The last of the six springs was assembled at Rotherham on 9th January. The springs will be delivered to the Llangollen Railway Works and fitted to the driving wheelsets once completed.  

Owen Springs have previously refurbished the tender springs for the Fowler tender that is being refurbished for use with 'The Unknown Warrior'

Frame Stretchers Delivered to Llangollen

Four frame stretchers were delivered to the Llangollen Railway Works during December 2011 and are awaiting fitting to the frames of 'The Unknown Warrior'.

The stretchers which were cast from new patterns made by Eddie Mocraft at the Boro Foundry, were machined before delivery to Llangollen. The four stretchers arrived at Llangollen in protective plastic sheeting.

The stretchers will be fitted between the frame plates of 'The Unknown Warrior' to enable a rigid assembly to be built. New drawings for the fifth stretcher are being completed. 

Genuine LMS Buffers Obtained for The Unknown Warrior

The LMS-Patriot Project has acquired a set of genuine LMS buffers for 'The Unknown Warrior'. Two of the Buffers will be used on the loco which is being assembled at the Llangollen Railway Works and the other two are suitable for the ex Barry scrapyard Fowler tender which was dismantled at Barry Rail Centre, in South Wales.
