1、Chapter 4,Railroads,Brief History,A significant role in the economic development of US from 1850 to 1950.20世紀後半開始衰落:The rise of alternate transport modes with superior services and/or cost characteristics, primarily motor carriers and pipelinesA resurgence in water transportationChanging needs of th

2、e US economy.Other modes growing faster, However, may experience a resurgence because of more aggressive marketing and growth in intermodal traffic.,History in Taiwan,劉銘傳興建縱貫鐵路清光緒十三年（西元1887），任命補用知府為鐵路商務總辦，六月開始由大稻埕向基隆舖設鐵路西元1891年完工通車，全長三十二公里，其中穿越獅球嶺的隧道全長五七三公尺，工程頗為艱巨，完工後在隧道南端口勒刻曠宇天開的碣碑，此碑仍保留在當地。西元1888年

4、.Taiwan railway need to face the competition after it become a private company.,Intermodal,Railroad company president said:Our service is not as fast as truck, but we have discovered that customers will accept a slower transit time in exchange for a lower rate, as long as service is consistent and w

5、e can usually provide a lower freight rate because our costs are less than truck.,Abandonments,1916,the railroad industry owned 254,000 miles of track. 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

6、remain competitive.Does Taiwan railroad need to abandon some trackage to remain competitive?,Abandonments,In some cases, all or part of the right of way was turned into hiking trails with some bridges left in place.Some became recreational facilities, like Gi-Gi lane up to Ali Mt.The abandonments we

11、adings, which are linked to the relative health of the domestic automobile industry, have increased to more than five percent of total carloadings, an increase of more than 40 percent since 1982.The railroad are still an ideal mode of transport for many different types of goods, high-value merchandi

12、se and raw materials alike.,Constraints,Railroads are constrained by fixed rights-of-way and therefore provide differing degrees of service completeness.If line-haul mileage continues to decline, the industry will become less service-complete and even more dependent on other modes of transportation

13、for completion of many types of moves.,Strengths,A large carrying capacity enables the railroads to handle large-volume movements of low-value commodities over long distances. Although pipelines compete directly with the railroads, they are restricted largely to the movements of liquid and gas.Railr

14、oad can handle almost any type of commodity by changing the hauling cars.,Strengths,Liability for loss and damage is usually assumed by the railroads.Steel wheel on steel railComparatively high percentage of goods damaged in transit.(3%)Incidence of loss is usually higher than on other modes because

21、nit train specializes in the transport of only one commodity, usually coal or grain, from origin to destination. 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

23、pelines).,Fixed Costs,Extensive investment in private terminal facilitiesFreight yards, which trains are sorted and assembledTerminal areas & sidings, where shippers and connecting railroads are serviced.Freight cars and other equipments.motors can use free of right-of-way, because they dont need to

24、 build roads.,Semi-variable Costs,Maintenance of Rights-of-way, structures and equipment,Variable Costs,Labor cost is the largest single element of variable costs for railroads.Fuel and power costs are the next largest group of variable costs.,Economies of Scale,Very large capital investment because

25、 of the cost incurred in buying land, laying tracks, building bridges, providing terminals, and providing right-of-way facilities.Equipment investment is significant.Maintenance of right-of-way structures also results in fixed costs.,Technology,Computers are playing a large role in every mode of tra

Railroad emissions(0.9 grams per net ton-mile) were 75 percent less than truck emissions.,
