Close coupling (railway)
A close coupling in the railway sector is a non-standardized coupling of two railway vehicles, which, compared to normal screw couplings and central buffer couplings, enables a shorter distance and a connection with a higher load capacity. Close couplings can only be disconnected by loosening screw connections in the workshop and are not disconnected in regular train operations.
Close couplings can be designed so that they can transmit compressive forces and the side buffers are not required; or each vehicle has only one central buffer to absorb the compressive forces close to the close coupling, which in turn only transmits tensile forces.
commitment
Close couplings are used in the vehicles of the Berlin S-Bahn , multiple units , container carriers , Leig units and car transporters. Heavy bulk goods wagons for transporting ore are often connected with a close coupling to form paired units. Close couplings usually also connect steam locomotives with their associated tender .
Close couplings on model railways
Close couplings on model railways are kink-resistant coupling devices which, by means of a link guide , enable the model vehicles to be closer together and more true to the original than is possible with classic, non-kink-resistant couplings. The backdrop ensures that the distance between the car bodies in the curves increases so that they do not touch and derail.
