Review and recommendations as part of our systems approach
Systems approach in design carefully considers the following:
Evaluating how “matched” wheel/rail profiles should perform, including areas such as rolling radius difference, stability, steering, stability, contact bands, and conicity:
Ensure that the profile design results in stable wheel/rail contact.
Angle of one radius to the other is the same for wheel and rail.
Prevent wheel hollowing through “pummelling” the profile
