Shape of teamwork

Your item ‘MMU helps put bullet trains on track’ (The Big Picture, 3 September) includes a statement regarding the wheel wear simulation programs which I would like to clarify.

The wheel wear prediction routines were developed in a collaboration between Manchester Metropolitan University and the Royal Institute of Technology, Stockholm, in a project funded by RSSB. The Vampire Rail Vehicle Dynamics software was developed by, and is a registered trademark of, DeltaRail (formerly AEA Technology).

Combining these two tools has allowed the accurate prediction of wheel wear and the emerging profile shapes.
