At WDB Ltd, we are proud to have been involved in the original manufacture of the hybrid engine flywheel for the Stourbridge Class 139 Parry People Mover between Stourbridge Junction and Stourbridge Town.

The lightweight rail vehicle has been successfully in service for many years, and its flywheel energy storage means it is highly energy-efficient, producing low emissions of pollutants and noise due to the prime movers running on gas, diesel or hydrogen, rather than overhead wires.

The flywheel has recently undergone refurbishment and balancing at our site. This refurbishment included the manufacture and installation of a new driveshaft, the removal and replacement of bearings, and dynamic balancing to ISO grade G2.5.
