In recent years, great alignment in heavy-load transportation under the weight, all sorts of foundation equipments have been severely fatigue period, showing that many problems, causes transportation production received great restriction, safety is facing a huge challenge, need to large prospective railroad lines renovation and equipment renewal. And explore how big alignment aristarchus overloaded train comprehensive transportation new technology research, the optimization scheduling organization plan from adding train dispatching logarithms, improve traffic density to improve interval through ability and goods conveying capacity. Restrict large prospective railway heavy-load transportation development is the main reason of the backward railway technology and equipment couldnt keep up with the current rapid development of coal volume needs, based on th
