The invention relates to a transport system (10) with a fleet of road vehicles (20) that can be supplied with traction energy at charging stations (30) installed on the road side. A road vehicle (20) has an electric traction drive (21), a rechargeable energy store (22) for traction energy and mating contacts (24) arranged on a vehicle roof (23). A charging station (30) has a charging mast (31), a pantograph-like actuator (32) which is hinged at its upper end (33) to the charging mast (31) and carries charging contacts (35) at its free lower end (34), and a controllable actuator (36) for the actuator (32) for lowering and raising the charging contacts (35). The road vehicle (20) can be positioned under the actuator (32) of the charging station (30) in order to charge the energy store (22) such that an electrical connection between the charging contacts (35) and the mating contacts (24) can be made by lowering the charging contacts (35). can be produced. According to the invention, a maintenance system (40) for the automated determination of an operating state of the road vehicle (20) and / or the charging station (30) is provided, which has at least one video camera (41) arranged at the charging station (30) for recording digital video images and an evaluation unit (42 ) for digital image evaluation, which is designed such that an operating state of the road vehicle (20) and / or the charging station (30) can be determined by image evaluation of recorded video images. This enables maintenance measures to be determined efficiently and as required.
