Abstract: To permit lateral deflection of a transport vehicle or car (1) which receives electrical energy from an overhead system (56) and, additionally, is guided thereby by guide rails (6), a connecting element in form of a telescoping rod (4) or a tension spring (4a) connects the vehicle to the overhead system (56) to receive electrical energy and, additionally, guidance information. In accordance with the invention, a control guideway (12) is located, for example laterally adjacent the overhead system (56), the relative alignment of the guideway with respect to the control rails (6) being sensed by the roller (15) forming a reference element, which, upon change of level of the guideway with respect to the guide rails (6) causes deflection of a roller shaft (16) coupled to a joint (11), which deflection is measured in an angle measuring sensor (11a) and transmitted as an error signal to a comparator (101) which tends to reestablish a predetermined angular relationship, for example 90.degree.
