Railway Electrification.
There are four chief attractions of electric haulage. One is great rapidity of acceleration. The next advantage is that the electric locomotive is always ready for use and can remain in service for practically the whole of twenty-four hours continuously. Under electrification the maintenance and operation costs are relatively cheap. Another essential benefit to be obtained is the ability of electrics to haul very long and heavy trains for there is practically no lim it to the energy to be taken by the locomotive from the catenary. Besides of all the existing kinds of traction the electric haulage is the most promising as regards speeds.
The electric rolling stock is of two types: locomotive-hauled trains and multiple-unit trains. Thanks to their rapid acceleration multiple-unit trains are most suitable for suburban railways with their frequent stops and frequent services. As to electric locomotives they are mainly used to haul long-distance goods and passenger trains.
