Also, I was told the unofficial reason is
late at night, train managers are often harassed
by drunken passengers, and putting them
at the front keeps them out of harms way.

That doesn't sound too plausible: drivers are (or were) instructed to drive
manually whenever there are a lot of drunks on the system, but this is
because of the probability of drunks falling off platforms in front of
trains.
