A toy vehicle for a racing game and a track for performance on vertical and horizontal surfaces. The vehicle carries an electric motor and draws power from a pair of conductive rails embedded in the track surface. Increased magnetic attraction between the car and the conductive rails is provided locally to enable the vehicle to ride on vertically extending track lengths without impairing horizontal performance. Increased magnetic coupling is also effective in enhancing vehicle performance on curves. Greater holding forces between vehicle and track on vertical surfaces is provided by increased width in the electrically conductive rails embedded in the track surface.
