THE pony truck for underconstruction Gresley‘P2’No. 2007 Prince of Wales has been delivered to the A1 Steam Locomotive Trust’s (A1SLT)
Darlington Locomotive Works following its fabrication by North View Engineering Solutions in the town.
The new pony truck is of a modified design to those fitted to the original members of the class, in order to avoid issues that afflicted the‘P2s’in this area. The A1SLT therefore commissioned DeltaRail (now Resonate) to use Vampire software to construct a virtual‘P2’and analyse the performance of the original Gresley swing link suspension design and a modified pony truck using side control springs.
This data, together with an LNER-revised design for the‘V2’ 2-6-2 pony truck arrangement, was used to redesign the pony truck for No. 2007 using side control springs and incorporating roller bearings.
