Research on Bogie Frame Lateral Instability of High-Speed Railway Vehicle

Table 2

The matching equivalent conicities between different worn rails and treads.

Wheel tread profile	Rail profile
	Rail 60	K865 + 350	K884 + 250	K884 + 650	K885 + 000
	Standard rail	Normal wear of rail tread	Gauge corner wear of rail	Wide tread wear of rail	Grinded rail
concave-worn tread	0.34	0.31	0.41	0.31	0.25
reprofiled tread	0.05	0.05	0.07	0.05	0.05
