Re-inventing the Wheel

Wheel maintenance accounts for a significant share of the maintenance costs of railway vehicles. Thus, engineers strive to design wheels that are ever more robust and better performing.

Shift2Rail-funded research has developed a new wheel made of Austempered Ductile Iron (ADI), which diminishes the tendency for polygonisation and reduces wheel and rail wear, noise emission and wheel mass.

ADI is a cast material characterized by a favorable combination of strength and ductility and high wear resistance. The new wheel is 10% lighter than current conventional models.
