Following the delivery of the wheelsets, the axleboxes and cranks were refitted (above), and the external diameter of the wheels turned in the wheel lathe ready for fitting the new tyres.
Below, with the wheelset standing vertically, the tyres are heated using an induction heater (seen behind and to the left) until they have expanded sufficiently to allow them to drop over the wheel centre.
Once fitted, the wheelsets are mounted in the wheel lathe and the outer profile of the tyres is turned to the final size.
