Conicity and rolling line offset values as calculated for HSFV1a on the APT test track near Widmerpool (IM-DA-062)

In conjunction with tests of HSFV1a on a stretch of the test track, the rail profiles were measured at various positions. The conicity values and rolling line offsets were calculated for the wheels of HSFV1a, as measured by WPMM l, and some unexpected results were produced. The track in...
