We are pleased to announce a new £210,000 appeal to manufacture the motion for new Gresley class P2 No. 2007 Prince of Wales. The A1 Steam Locomotive Trust has therefore set itself the challenge of raising £210,000 through The Motion Club from 175 supporters each donating £1,000 (plus Gift Aid) to the project in up to eight payments of £125 by standing order.

If the project is to remain on schedule to complete No. 2007 by 2021, the Trust needs to order the motion in 2018. Following the success of The Founders Club (to get the project to the point of cutting the frames), The Boiler Club (to fund the construction of the boiler) and The Mikado Club (to wheel the locomotive), The Cylinder Club (to make the cylinder block), the Trust has decided to establish The Motion Club to raise an estimated £210,000 required to manufacture No. 2007’s motion.  You can download The Motion Club leaflet here and the club registration and standing order forms here.

In return for supporting this appeal, special benefits for members of The Motion Club include:

  • Opportunity to buy ticket (seat already reserved) on one of the first trains hauled by No. 2007 Prince of Wales
  • Reasonable access to No. 2007 at all times
  • Opportunity to buy exclusive Motion Club badge
  • Opportunity to join one of the teams building No. 2007
  • First choice of other components to sponsor
  • Special Motion Club day with Tornado
  • Special limited-edition version (signed/numbered) of Stuart Black’s drawing of No. 2007 Prince of Wales.

The work involved in designing and manufacturing the motion includes:

  • Redesign of coupling and connecting rods to use modern material (pre-war nickel chrome steel alloy proved prone to fracture
  • Incorporation of late-pattern BR-type continuous white metal lined crank pin bearing bushes
  • Use of the late-A1 design of inside connecting rod which overcame the tendency for the original design of inside connecting rods on LNER ‘Pacifics’ to big-end failure
  • Open die forging of six coupling rods, two outside connecting rods and the inside connecting rod and strap
  • CNC machining of all rods
  • Manufacture of oil box lids, coupling rod knuckle pins, nuts and washers and bearing bush keys
  • Casting of leaded gunmetal and phosphor bronze castings of crank pin bearing bushes
  • Machining and white metalling of bearing bushes
  • Fitting oil box tops
  • Assembly of bearing bushes to rods
  • Polishing rods.
