The vehicle includes a plurality of steerable axle assemblies, each axle assembly having an axle arrangement, a pair of upper wheels journalled on the axle arrangement and engageable with respective upper running faces; and a pair of lower wheels journalled on the axle arrangement and engageable with respective lower running faces. A steering arrangement urges the axle assemblies to align with the track arrangement. A loss sensing arrangement which senses a loss of adhesion or an imminent loss of adhesion of the upper wheels with respect to the respective upper running faces. A signal arrangement generates a signal indicative of one of the loss of adhesion and the imminent loss of adhesion of the upper wheels with respect to the respective upper running faces. An actuating mechanism forces the second set of wheels into running engagement with the respective lower running faces in response to the signal from the signal arrangement and with a force of engagement dependent on the signal from the signal arrangement.
