  • Trains run from about 05:30 to around midnight. After that it's a Night Owl bus or a taxi — check the last train page before a late night.
  • Luggage: fine on the subway, but transfer passages at big interchanges can be long. Look for the elevator sign rather than the escalators if you have suitcases.
