In electrified areas, jointless track circuits require fewer impedance bonds than any other double rail traction return track circuits. Disadvantages of jointless track circuits: Restrictions on placing impedance bonds, hence any connection for electrification purposes, in or near tuned zones as this may upset the filter properties of the tuned ...
An axle counter detection point in the UK Axle counter for automatic railway crossing (Slovenia). An axle counter is a system used in railway signalling to detect the clear or occupied status of a specified section of track.
In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit. [1]Quantitatively, the impedance of a two-terminal circuit element is the ratio of the complex representation of the sinusoidal voltage between its terminals, to the complex representation of the current flowing through it.
