Electrified railway, also known as electrified railway, is a railway that is mainly operated by two types of railway trains, electric locomotives or multiple units (commonly known as trains). The traction power of electrified railways is electric locomotives, which do not carry energy, and the required energy is provided by the electric traction power supply system. The traction power supply system mainly refers to two parts: the traction substation and the contact network. The substation is located near the railway and will transmit the current from the power plant through high-voltage transmission lines to the overhead contact network above the railway. The contact network is a device that directly transmits electrical energy to electric locomotives. Although electrified railways have a large investment, the completed transportation volume after electrification is large, with high transportation income and low transportation costs. The required investment can be repaid in the short term
