It is generally held that the most efficient method of railwayoperation,and ultimately the most economical,given a reasonably cheap electricitysupply,is with electricity as the motive power.The electric locomotive is notdependent,like its steam counterpart,on the competence of driving and firingor the quality of the fuel burned.On the other hand,the speeds that will bepossible with any given load are completely predictable and apart from signalor permanent way checks,or other delay-producing casualties,exact observanceof schedule times can be guaranteed within narrow limits.With such accurate timetableobservance trains can be operated with shorter turnaround times at terminals,which means that more intensive use can be made of rolling stock than isgenerally possible with steam power.
