Do they have a better execute than lighting? It seems like this execute has been over used.
Even though I will not ignore the problems of China high speed railway, I am still a firm supporter of its building. To me, building for the future and the problems of building can be independent issues.
I'm not saying we don't need it. Like you, I'm a firm supporter to it too...
The problem is, do we need to build it that "FAST" without proper planning? If it's in Japan, I think if one train is being hit by a lighting, all the trains on the same section of track will stop automatically, just like it's in earthquake...
IMO, this collison accident can certainly be prevented (it's a dumb human mistake)...
If safety is not the first "priority" in the design, the rests are pointless...

I don't think we need to build this fast. I believe China only need two major connection routs for the current stage - one is Beijing-Shanghai-Guangzhou-HongKong, and the other one is Shanghai-Nanjing-ChangSha-Chengdu-ChongQing.
For now - yes, I see the demand, for future - there should be more routes as Peter stated...
But, the project is just too fast, too fast... No one is pushing them to run the project that fast except for political reasons...
What does "FAST" mean? Advance, progress, good... You name it...
"FAST" means "NOTHING" if it's not safe... You can't compare the high speed rail in China with Shinkansen, they are obviously at different levels (One is built to "SHOW OFF", the other is built to "LAST"). For Shinkansen, you hardly hear any big accidents they have at all in their history...

I believe they should just build a few major connecting routes for now. To allow the opportunities to mature the technologies, mechanical productions, railway construction, operations and management, and market demands.
For examples, Shanghai only had two subway lines for years. One was built under Germany guidance (I believe my memory is correct) and the other one was built by its own (it had quite a few problems when it was first put into operations). When the time came, it just expanded the subway lines to more than 10 just in 3 years.
Therefore, China shouldn't expand its high speed railway networks to the current size and at the current speed. Of course, 為政績搏上位 should be the major motive.
Another major concern I have is the quality for maintenance, the railway is just way too long...
It's almost certain that when time goes by more and more accidents will be ahead... The authority may not have input enough funds when the maintenance costs are already high...
