A railway is a complex engineering system and thus the construction of a new railway infrastructure or the modernisation (refurbishment) of an existing railway infrastructure requires systems overview. Electrified railways can require very high output (up to several MVA) electrical systems and power electronic systems that are characterised by their non-linearity (producing harmonics). In an electric railway the locomotives, which move with the trains, have to be supplied via sliding contacts from a supply line, called the catenary or overhead, or a trackside conductor rail, which is installed along the track. The current generally returns to the substation via the rails, a separate return conductor and via the earth. A detailed description of the railway and its core components is covered in Chap. 2.
