Underground trains (U-Bahn) run from about 5.00 am in the morning to about midnight, except weekend nights and the nights before holidays with continuous service. Trams and buses normally stop running earlier. A detailed timetable is available at each stop or with the qando app on your mobile. Night buses run every night along the city’s most important routes. Public transport in Vienna is very gay-friendly. Wiener Linien takes part in the Rainbow Parade every year.
