Fire­box throat­plate is the fi­nal piece in ‘Pa­triot’ boiler jig­saw

Steam Railway (UK) - - New-Build News -

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.
