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.
