Delivering world-class products in a competitive market


We have a long and successful experience of reconditioning engine components for the Rail Industry and worked for many years with British Rail and Bombardier to keep the Paxman and Deltic engines healthy and in service. We are still reconditioning these same components, more especially nowadays, for foreign navies who utilise the same engines at sea. We have used our skills and experience to introduce other types of engines to our reconditioning portfolio, please enquire if you require liners, piston crowns and cylinder covers reconditioning. Any liners up to 440mm can be reconditioned and we have specifications and drawings for many liners and components associated with engines powering locomotives.
