Hi Madridman,
It seems that you don't remember what I told you by e-mail:
I've been trying to get a copy of the bus schedules at the boths in Puerta del Sol, Callao and Cibeles but they *don't publish them* anymore. I will try to check it again at today, but I asked about it lots of times in the past years.
Go to the tourist office and ask for a free maps with the routes marked in red on the map.
By the way, ilovemadrid, I would recommend taking the subway instead. Though buses are quite good, traffic jams make them sometimes arrive.
Regards,
Antonio
