You have a choice of 54 day lines and 11 night routes. Day lines are numbers 100 to 149, Express routes 400 to 435, and fast routes are marked with letters. Night lines are numbers 240 to 259. Express, fast routes and night routes require more expensive tickets.

You will be able to find details of routes and timetables at the web site http://www.zdik.wroc.pl/. Unfortunately it is in Polish only. To get the timetable go to KOMUNIKACJA and then ROZKŁADY, then enter the line you are interested in and get the timetable and route by picking the bus or tram number and selecting the stop you want for the timetable details. It may be a bit complicated but with a little practice and some minimal Polish vocabulary you should manage.
