Today, more than half of that is gone, enough to circle the Earth three times.The railroads had to abandon significant portions of rail trackage to

Many times the shipper owns cars, and the train is, in effect, rented to the shipper for a particular period of time.,Cost Structure,Fixed CostsSemi-variable CostsVariable CostsLaborFuel,
22、Fixed Costs,The railroads, along with the pipelines, are the only modes that own and maintain their own network and terminals. Therefore, there are a large proportion of indirect fixed costs.Mostly operation, maintenance and ownership of rights-of-way, which are not found in other modes(excluding pi
