Hong Kong MTR is only sort of privatized. It is operated by a publicly traded company, but the government owns a 75% stake.

Most of the Hong Kong MTR lines use an older implementation of CBTC which doesn't support fullly unattended operation, which is why they are looking to upgrade. New York is in the process of implementing CBTC on some lines, but their implementation won't support fully unattended operation either.
