Firebox throatplate is the final piece in ‘Patriot’ boiler jigsaw
LNWR Crewe is set to begin assembling the boiler for ‘Patriot’ No. 5551 The Unknown Warrior, with the completion of the outer firebox throatplate. This awkwardly shaped sheet of steel with its reverse bend, formed by Tyseley Locomotive Works, is the final piece of platework needed for the Fowler ‘5XP’s’ boiler. It had to be made in two sections and both have been sent to Crewe for welding together. The sole remaining large casting for the boiler - the superheater header - is also due to be made shortly, and it is the intention to complete the boiler this year, in good time for the locomotive’s target steaming date of November 2018 to mark the centenary of the Armistice. The leading driving wheelset returned to Llangollen in early February, having been sent to the South Devon Railway for the eccentric keyway to be re-machined. The opportunity was taken to fit the rear cylinder covers and slidebars, taking advantage of the extra working space without the wheels and crank axle in place. Also delivered to Llangollen recently were the inside and outside eccentric rods, and the crossbeams and pull rods for the brake gear, meaning that all the parts for the latter are to hand. The arrival of the inside connecting rod is imminent, and the inside combination lever has been ordered.
