Case study of four battery-powered methods to run electric trains on non-electrified lines

Four types of e.m.u.s operation methods will be introduced to use storage batteries as the power source for medium-distance non-electrified lines over 100 km, and compared them with will full-line electrification. Accoding to the case study, running a train by connecting and releasing a battery source car has the advantage of the viability of the vehicle and the total cost of the first over nine decades.
