Abstract
The invention relates to a self-propelled vehicle (10) provided only with rail-engaging rolling means (18) comprising: a chassis (14); a working surface (16) connected thereto for supporting equipment, materials (20) and personnel; and positioning means (22, 24) connected to the chassis for lifting the vehicle and moving it laterally with respect to a direction of rail travel between a trackside location and an on-track location (12). A lifting apparatus (28) is mountable on the chassis and moveable along the length of the working surface (16). By providing only rail-engaging rolling means (18), the height of the vehicle's overlying working surface (16) above the track (12) and surrounding ground is significantly reduced as compared to existing dual purpose road-rail vehicles. The vehicle is capable of working safely below live overhead lines and alongside tracks open to traffic thus avoiding the need to for full closure of tracks during maintenance and inspection works.
