I’m sure I will get flamed, but when I went to Beijing, I was very impressed with their subway system. Very fast and efficient. They also had messages in English. That and the new International Airport terminal were impressive. Everything else, not so much.
I've never been to Beijing...but I have been to Guangzhou and Shenzhen,two major cities in the southeast...no too far from Hong Kong (Shenzhen is right over the border from Hong Kong).
I've ridden Hong Kong's Metro,the "MTR",many times.I've gotten pretty good at in fact (thanks to all the English signage).The MTR is world class in every way...but then *it* was built by the British before they left.
My main objection to having Chinese made cars for the T is jobs and the economy.China is our enemy and anything we do to strengthen their economy hurts us in many ways...economically,diplomatically and militarily.If the cars can't be made here I'd much rather them come from the places I mentioned...none of which are our enemies.
