Abstract
An articulated railroad vehicle having two or more body portions is supported on three or more single wheel set trucks. Each truck is pivotally attached to a vehicle body portion. Sensing elements detect the angle between the articulated body portions. The output from the angle of articulated sensing element means is used to guide each of the wheel sets to a radial configuration when the vehicle negotiates a curve.
