A traffic system includes: a vehicle having a power-receiving section on an outer surface thereof; and a ground facility having a power-supply section for supplying the power-receiving section with power by coming in contact with the power-receiving section. The power-supply section has a spring for applying a biasing force to a power-supply shoe in the power-supply section toward the power-receiving section. The power-receiving section has a flat surface that extends along the outer surface of the vehicle, and tapered surfaces that are connected to the flat surface in the forward and backward moving directions of the vehicle and guide the power-supply shoe to the flat surface against the biasing force to bring the power-supply shoe into contact with the flat surface when the vehicle moves backward and forward.

A magnetically clampable rail shunt (1) comprising two magnetic clamps (10), each clamp having a magnetic device for attaching the clamp to one of two parallel railway rails (R1, R2) of a railway track by magnetic force, and an electrical conductor (20) electrically connecting the two magnetic clamps (10) for shunting the two parallel railway rails. The rail shunt (1) is characterised by a variable electrical resistor assembly (30) for adjusting the electrical resistance of the rail shunt (1), said variable electrical resistor assembly (30) being connected in series between the two magnetic clamps (10) via said electrical conductor (20). Preferred application to testing of track circuits.

A simulation system for a current collecting surface of a C-shaped contact rail includes a double-headed rail and a limiting plate. A current collecting end surface of the double-headed rail has a same current collection area as an actual C-shaped contact rail. The limiting plate matches the inner contour of the C-shaped contact rail. A constructed test line can simulate the current collecting status of the C-shaped contact rail. The limiting plate and the existing double-headed rail are combined, and compared with reproduction of the C-shaped contact rail, the manufacturing cycle is short, the costs are low, and it is applicable to the test line.
