Improve the road system first.

Hey little six legged friend who helps spread malaria, It's no longer called a bullet train, there is a restriction on.... capacity of the magazine via your own darling Diane Fienstien. You can now call it a peace train. "Hill tribe people" can like it or lump it. Ever hear that expression about the dog looking at the airplane? Ma yeng krung bin. The train won't stop in Laos, they'll be lucky if it slows down for Jihong.

But how else will we meet the demand for all those Lao people eager to go at bullet speed to China. Don't we all want to flock there.
There will be no "bullet" train. The land is far too rugged, and under-populated, for affording such a passenger-focused mode of tranbsportation. If anything, anticipate a freight-way (slow-rail or sealed road) route.
Bulet train for whom?

Here comes Rocky Mountains hill tribe man. You must have poor eyesight if you needs a machine gun to take down an defenseless elk. stop paying your NRA dues and use the money to buy some chicken.
#13 makes a lot of sense.
#12 whilst I doubt that the line will ever be built one thing is certain that if it is there is NO way that train would not stop in laos. Why would they ever allow the line to be built. However the question remains would the locals be able to afford it
The line if it ever comes to fruition will run from China into Thailand , hopefully a fast link in between Chiang Mai - Bangkok , then it will run on through to Cambodia going via Pattaya and on through to Phnom Penh then onwards to it's final destination in Saigon ..
The other route will go from Chiang Mai - Bangkok - Kuala Lumpur -Singapore .. This could very well be a high speed link ..
But i can't see any link going through Lao , the financial implications plus the Maintenance issues that would come up would not make it viable for any rail link to be built through Lao ..
concentrate on building a sealed road network first , mind you if the British had been in Lao , Cambodia and Vietnam instead of the French we would most likely not be having this discussion as the Brits would have left a perfectly good transcontinental rail network in Indochina , just as they did in Africa , India , and Malaysia instead of the crappy half hearted attempt at building a road network that the French left half built ...

In more seriousness, I read the long range plans from Tlands development of high speed rail don't include any plans for Nong Khai or Mcdahan http://www.zenjournalist.org/wp-content/uploads/2013/02/nomurathai.pdf I doubt the Chinese would want to build a dead end to Vientiane. I remember ongoing discussion also about how large a swath of land the Lao PDR would be willing to give away with the RR. I remember 1.5km on both sides is what the Chinese wanted, which would de facto give them hundreds of km of LPDR.
Only proletariate Kalashnikovs here skeeter guy. Chickens close to frozen.
But imagining the " tribal people gaping" at a monster destroying their environment slightly reminds me of the steamhorse ploughing through the hunting grounds of the red Indians. Shouldn't we be more aware?
lol
#16 From China to Chaing Mai the line will either have to go through Burma or Laos
saw somewhere when I was in Thailand earlier this year that the Thai PM had promised the line would be built before she left office in 3 years time - no doubt she will follow in her brothers footsteps and declare the line open even if there is no track and trains!
