Hong Kong's MTR has consistently been the most well run private transport service I have had the privilege of riding. (I could be mistaken, the MTR is privatised, right? I do know all the buses are.)<p>The only surprise I read was that they consider the CBTC signal system as outdated and in need of replacement. In fact, it might've been here where I read an article about how New York (or perhaps Chicago) should switch to CBTC, but can't for a number of legacy reasons.
