CONVENTIONAL VERSUS SELF-STEERING RADIAL TRUCKS FOR HIGH-SPEED PASSENGER TRAINS
The performance of self-steering, articulated and non-articulated trucks on high-speed passenger trains was compared to a standard conventional passenger truck. Linear, lateral stability analyses and quasilinear, steady-state curving analyses were used to evaluate criteria of a design speed of 125 mi/h (200 km/h), and wheel tread and rail head wear in curves. Based on the results of this analytical study, the self-steering articulated truck would reduce wear in curves by a factor of two. However, an improvement in the steering characteristics of conventional non-articulated trucks would reduce wear in curves by a factor of four.
