磁悬浮列车虽然具有这么多的好处,但到目前为止,世界上只有上海浦东磁悬浮铁路真正投入商业运营
上海段约30公里的线路设计投资为100亿元人民币,而德国的两条线路,一条36．8公里长,将耗资约16亿欧元；另一条长度78．9公里,则将耗资32亿欧元（1欧元约等于10元人民币）.实际施工中,根据地形、路面及设计运送能力的不同,当然造价也会相差较大.但无论如何,一公里的路线至少需要3亿元人民币的投资,也就是说,1厘米线路就得花上3000元!
原理：利用磁铁吸引力使车辆浮起来的磁悬浮列车,用的是“T”形导轨,车辆的两侧下部向导轨的两边环抱.在车辆的下部的内翻部分面上装有磁力强大的电磁铁,导轨底部设有钢板.钢板在上,电磁铁在下.所谓电磁铁,就是一个金属线圈,当电流流经线圈时,能产生磁力吸引钢板,因而车辆被向上抬举.当吸引力与车辆重力平衡,车辆就可悬浮在导轨上方的一定高度上.改变电流,也就改变磁场强度,使悬浮的高度得到调整.另一种磁悬浮列车,采用相斥磁力使车辆浮起.它的轨道是“U”形的.当列车向前运动时,车辆下面的电磁铁就使埋在轨道内的线圈中感应出电流,使轨道内线圈也变成了电磁铁,而且它与车辆下的磁铁产生相斥的磁力,把车辆向上推离轨道.
利用相斥磁力悬浮的列车,一开动很快就可以加速到时速50公里,跑了50—60米的距离之后,便在轨道上悬浮起来.列车沿着地面越“飞”越快,目前最高可以达每小时550公里（理论上可以到更高速）.

Although maglev has so many benefits,but until now,there is only one maglev in the world,Pudong Shanghai Maglev,turned into commercial operation really.
The 30 kilometers’ Shanghai section prepares an investment of 10 billion Yuan.But,in German,there are two maglev rails; the one is 36.8 kilometers which cost 1.6 billion Euros,and another the 78.9 kilometers rail costs 3.2 billion Euros (1Euro is about 10 Yuan).
In actual construction,based on the terrain,pavement and transport capacity,there will be a great different in the cost,of course.Whatever,one kilometer of maglev rail will cost 300 million Yuan at least.That mean,one centimeter is cost 3000 Yuan.
Principle:
The vehicle which using magnetism of electromagnet to be floating,using a T-type rail,and the both side of vehicle’s bottom surrounds the both sides of the rails.On the turned inward plane of the bottom of the vehicle fixes a powerful electromagnet,and the bottom of the rail sets steel plates.Steel is on top,electromagnet is on bottom.
The so-called electromagnet,in exactly,is just a metal coil.When the current flowing through the coil,there is magnetism produced,and then it can attracts the steel,as a result,the vehicle is been floating.When the magnetism and the gravitation of the vehicle can be balanced,the vehicle will float in a certain height above the rails.To change the current,the strength of the magnetism can also be changed,so the floating height is adjusted.
Another type maglev train using the repellent force of magnetic to keep floating.Its rails are U shaped.When the vehicle moving forward,the electromagnet set on the bottom makes the coils which buried in the rail induct current,so the coils in the rails are now turned into electromagnet.So the two electromagnets generate a repellent magnetic force to push up the vehicle above the rails.
Maglev train using the repellent magnetic force can quickly speed up to 50km/h,and after it run about 50-60m,it will float up the rails.The train can be “flying” along the ground,current,the top speed can reach to 550km/h (higher in theory).

Although maglev train owns some many benefits, however, it's only PUDONG(Shanghai Province) maglev railway came into business field by now.

Although maglev train owns some many benefits, however, it's only PUDONG(Shanghai Province) maglev railway came into business field by now.
The design of Shanghai Part ,which is about 30km, costs 100 billion, while two line of Jerman, one 36.8km, the other 78.9km, will cost 32 billion euro(1 euro is about 10 RMB). During the real construction, it changes largely according to the difference of terrain,roadbed and transport ability. Anyhow,1km line costs at least 3 billion RMB, in another word, 1 cm railway line cost about 3000 RMB!
