Question

Describe the advantages of electrification of railways


​

Answer 1

Explanation:

A railway electrification system supplies electric power to trains without an on-board prime or local fuel supply. Electric railways use locomotive to haul passengers or freight in separate cars or with their own motors. Electricity is typically generated in large and relatively efficient , transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an utility. The railway usually provides its own distribution lines, switches and transformers.

Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: over head line, suspended from poles or towers along the track or from structure or tunnel ceilings; third rail mounted at track level and contacted by a sliding "pickup shoe". Both overhead wire and third-rail systems usually use the running rails as the return conductor but some systems use a separate fourth rail for this purpose.

Explanation:

Electric-powered trains have a number of advantages over diesel engines. They have quicker acceleration, lower fuel costs, produce fewer CO2 emissions and are lighter, meaning they create less wear on tracks.A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains.
