I haven't heard of China selling trains to the US (if so it would be another irony as the US used to be the unsurpassed leader in the railway industry!) though I know that they are trying to interest California in high speed rail. The problem is that the Chinese rail industry is outrageously corrupt (the New Yorker did an extensive piece some time ago about the inefficiency and corruption of the state sponsored industry). There have been many accidents due to the great rush to expand service, the failure to ensure safety and the vast amounts of money earmarked for rail projects that have been stolen by bureaucrats). It's true that the new Chinese trains are better than what they replaced, but they would be far better had they been manufactured in France, Germany, or Spain. Argentina could create its own rail manufacturing industry but despite repeated exp<b></b>ressions of enthusiasm for rail passenger service (Nestor often spoke about his determination to revive rail passenger service), the Kirchners have done little to improve the situation. Of the coastal trains, service to Mar del Plata has been reduced to something like two trains a day. Pinamar service, revived by Duhalde when he was governor of BA Province, has not run for years under the Kirchners. I assume the trucking unions have had something to say about intercity rail service.
