The Cylinder Club – Complete!

£100,000 appeal to make the cylinder block for No. 2007 Prince of Wales is concluded.

We are delighted to announce the £100,000 appeal to make the cylinder block for new Gresley class P2 No. 2007 Prince of Wales has reached its 100 member target. If the project is to remain on schedule to complete No. 2007 by 2021 we need to order the cylinder block in 2018. The A1 Steam Locomotive Trust has therefore set itself the challenge of raising £100,000 through The Cylinder Club from 100 supporters each donating £1,000 (plus Gift Aid) to the project in up to eight payments of £125 by standing order.

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 established The Cylinder Club to raise an estimated £100,000 required to make No. 2007’s cylinder block.  Thanks to all of you who supported this initiative – the other clubs are still open!

In return for supporting this appeal, special benefits for members of The Cylinder Club included:

  • 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 Cylinder Club badge
  • Opportunity to join one of the teams building No. 2007
  • First choice of other components to sponsor
  • Special Cylinder Club day with Tornado

The work involved in designing and manufacturing the new cylinder block included:

  • Convert the original P2 class one-piece casting into a welded fabrication including Finite Element Analysis (FEA) to check for structural integrity
  • Improve the layout of the valves to reduce the clearance volume (which affects cylinder efficiency)
  • Re-route the steam and exhaust passages to physically separate them to prevent incoming steam from heating the outgoing exhaust
  • Increase the size and improve internal streamlining of steam passages along Chapelon lines to increase maximum power and improve economy
  • Reduce the overall width of the cylinder block to provide Prince of Wales with the widest possible route availability on the main line.
  • Manufacture the cylinder block including:
    • Producing the welded fabrication
    • Stress relieving
    • Grit blasting and painting with high temperature paint
    • Machining
    • Fitting cylinder liners and valve seats
    • Manufacturing and fitting cylinder and valve covers
    • Hydraulic testing the assembly.
