You pay with your eletronic card when entering a station and may change buses as often you want without paying again, unless you stay in the station.
There are buses that stop at every station and express buses that only stop at certain ones. Have a look at the map where you wanna go and which bus to take.
Unfurtunately handout map are very difficult to get. Mostly at the portals you have to ask the people with the orange jackets (Bogotá para vivir) and they might have one.
Hours are weekdays and saturdays:
5am to 11pm
(that's when the first and last busses leave the portals!)
Sundays: 6am to 10pm
During rush hour Transmi is always very crowded and it can be uncomfortable... if you manage to get on a bus...
That's why Transmilenio is also called "Transmi-lleno".
Usually routes 1 to 3 are less crowded than the express buses.
