Answer a iThe benefits of an electrified railway when compared with conventional diesel motive power are as follows Electrified railways operate at lower operating costs and higher efficiencies They make less noise they are more strong robust and responsive They are best suited for city areas and tunnels for transportation because there are no smoke emissions like diesel engines Electricity can be generated without burning natural resources Due to the regenerative braking systems some electric traction energy can be reused by other trains It is a better and a viable alternative from environmental sustainability point of view iiThe two main types of electric traction systems that exist are as follows Direct Current DC electrification system 3phase Alternating Current AC electrification system Some of the advantages of DC electrification system are as follows For same operating conditions DC consumes less energy than AC system The equipment in DC traction system is less costly lighter and more efficient than AC traction system It causes no electrical interference with nearby communication lines It has less distribution cost Fewer See Answer
