3、 wheel railways.The primary advantage is maintenance.Because the train floats along there is no contact with the ground and therefore no need for any moving parts.As a result there are no components that would wear out.This means in theory trains and track would need no maintenance at all.The second
4、 advantage is that because maglev trains float,there is no friction.Note that there will still be air resistance.A third advantage is less noise,because there are no wheels running along there is no wheel noise.However,noise due to air disturbance still occurs.The final advantage is speed,as a resul
5、t of the three previous listed it is more viable for maglev trains to travel extremely fast,i.e.500 km/h or 300 mph.Although this is possible with conventional rail it is not economically viable.Another advantage is that the guide way can be made a lot thicker in places,e.g.after stations and going
6、uphill,which would mean a maglev could get up to 300km/h(186mph)in only 5km where currently takes 18km.Also greater gradients would be applicable.uThe disadvantages with Maglev There are several disadvantages with maglev trains.Maglev guide paths are bound to be more costly than conventional steel r
7、ailways.The other main disadvantage is the lack of existing infrastructure.For example,if a high speed line between two cities is built,then high speed trains can serve both cities but more importantly they can serve other nearby cities by running on normal railways that branch off the high speed li
8、ne.The high speed trains could go for a fast run on the high speed line,then come off it for the rest of the journey.Maglev trains wouldnt be able to do that;they would be limited to where maglev lines run.This would mean it would be very difficult to make construction of maglev lines commercially v
9、iable unless there were two very large destinations being connected.u城际列车是直达型火车,如上海到北京的城际列车是直达型火车,如上海到北京的Z字头列车,运行中一字头列车,运行中一站都不停靠。国内正在建设高速铁路,这种铁路运行方式就会站都不停靠。国内正在建设高速铁路,这种铁路运行方式就会采取城际列车的优点,实现大中城市之间快速连接。采取城际列车的优点,实现大中城市之间快速连接。u火车是常规型列车,如上海到成都,中间停靠很多城市车站。火车是常规型列车,如上海到成都,中间停靠很多城市车站。u轻轨是城市内部轨道交通,运送能力较小,车
10、体内部宽度较大,轻轨是城市内部轨道交通,运送能力较小,车体内部宽度较大,适合中小城市内部交通利用。如无锡、苏州,上海有轨道三号适合中小城市内部交通利用。如无锡、苏州,上海有轨道三号线就是轻轨明珠线。线就是轻轨明珠线。u地铁也是城市内部轨道交通,运送能力比轻轨大一倍多,车体地铁也是城市内部轨道交通,运送能力比轻轨大一倍多,车体内部较窄,适合大型城市高峰时段人流量大的使用。上海北京内部较窄,适合大型城市高峰时段人流量大的使用。上海北京广州都有地铁。广州都有地铁。u磁悬浮列车是目前国内运行速度最快的城市轨道交通,只有上磁悬浮列车是目前国内运行速度最快的城市轨道交通,只有上海有磁悬浮,它是车体在运行中
11、悬浮于铁轨之上的列车,每趟海有磁悬浮,它是车体在运行中悬浮于铁轨之上的列车,每趟列车的车厢节数较少,运载能力比地铁和轻轨都小,但是运行列车的车厢节数较少,运载能力比地铁和轻轨都小,但是运行速度最快,最大时速达到速度最快,最大时速达到400公里公里/小时,如果上海到杭州磁悬小时,如果上海到杭州磁悬浮建成后,照此速度只要浮建成后,照此速度只要20多分钟就可以到杭州西湖赏景了。多分钟就可以到杭州西湖赏景了。1.super power 2.economic growth 3.domestic sector 4.various services 5.calm and comfortable 6.best
