Between 2001 and 2009, a series of field, laboratory and theoretical studies were conducted with FRA sponsorship to better understand the wheel/rail interaction on Amtrak’s multi-user Northeast Corridor. The development of a new wheel profile, optimized rail profiles, friction management practices and a grinding strategy were key aspects of the program. The experience gathered over an eight year period, including many lessons learned, has been collected and provides a template for how optimization of the wheel/rail interaction can be undertaken on high speed, shared use railway corridors.
