talking about high speed train's cost (3)
3. maglev, that's industry policy.
today's china, one hand PHD hard to find job, missile engineer clean shoes for people on the street in XI-AN. other hand pay huge money to buy automatical control system technology from foreign company. what's the industry policy in china? who is the one make policy there?
the technology of missile are much difficulty than high speed train. because missile in much higher speed, and nothing to hold it. high speed train are hold by rail way or maglev hold by guideway. you can set many sensor on railway to contral the train.
why there is no job for missile engineer in china and nobody can design high speed train? very hard to understand.
why the speed have to above 300km? is for fun? that's great. life need fun. but not the time for so much spending. is for show off? that's good. if china have this technology why don't show it off. but acturely china don't has this technology. just show japaness tech, franch tech or germany tech. and show chinese PHD can't find job but spend huge money to buy technology. show the world chinese missile engineer clean shoes on street but spend huge money to buy automatical control system technology. very funny.
why the speed have to above 300km? if use 200km system not work? that's much economic.

武汉至合肥高速铁路今年下半年正式动工，三年半后，武汉至合肥2小时到达，而经此铁路线武汉至上海的行程缩短为6小时。
据悉，目前武汉到合肥需要10个小时，这条高速铁路是国家规划的新的沪汉蓉通道的重要组成部分，东起合肥，穿越大别山腹地，经六安、麻城至武汉，线路全长350多公里，项目建设投资预计超过187亿元，设计时速为200公里。
据悉，该工程预计2007年建成，届时，从武汉坐火车到合肥将只需2个小时，而经此线到上海，将少花2／3时间，只需6小时即可到达。
if use 200km system, 350km cost RMB 18.7 billion. 1300km only cost RMB 70 billion.
for 300km/h, 1300km need 4.3 hours. for 200km/h, 1300km need 6.5 hours. there are 2 hours defference. what's the matter for 2 hours deffrence? and need more than 100 billion to catch up this 2 hours.
i think the reason is to upgrade industry leve. that's why need fast than 300km/h. use maglev technology is the railway industry policy. is for upgrade whole country's industry leve. not just railway industry. not just raise transportation ability.
that's not the reason to give up the maglev as there is no long distance maglev system on the world. acturely it's funny. before shanghai set up commercial use maglev, there is no maglev in commercial use at all.
maglev can't share existing rail system also is very funny story. do we ever hear japaness Shinkansen train runs on regular railway system in 30 years? or do we ever hear japaness regular trains run on Shinkansen line in these 30 years?
what i care is why japan only built ONE Shinkansen let it become a famouse fast train maker, and china build so many lines still don't have the technology?

i am quite wonder. what's the industry policy in china?
don't tell us china don't have scientist and engineer. many PHD can't find job in china now.
if the convertional high speed train is the only choice for beijin-shanghai line, should build it in 200km system first. upgrade speed later. save the money for the train factory to upgrade their leve. should set up a developing fund for fast train technology. the train factory which has most PHD are qualified the fund. because this is a PHD job not a college graduated job.
what is the trasportation industry policy in china? i am not clear. but i think should include save energy and save environment. maglev do save energy and save environment. so which should get policy support.
shanghai maglev dose not get policy supporting yet. it shouldn't competition with airport bus by rolling down the price only. airport bus also not a fully competition business.
to save the energy and environment, shanghai airport should let the airport bus pick up passenger at LONG-YANG station. only taxi and maglev get in airport. but maglev and airport bus should divide profit. and use one ticket.
