Give priority to developing a suitable solid wheel option to replace tyred wheels on Electric Multiple units.

This has been carefully studied. The Ganz Mávag wheel set has been designed in such a way that solid wheels can only be fitted if the wheel set is completely stripped of axle bearings, and brake discs or drive gear and suspension bearings, each time wheel replacement is carried out. This would dramatically increase the cost of wheel refurbishment and introduce further possibilities for error, so it is not intended to proceed with changing to solid wheels at this stage.
However it is intended to specify solid wheels for future orders of passenger rolling stock.
