Thanks very much for the valuable info, tips and links.
As for iPhone apps, I took a quick look at iBART, it seems to be very focused on planning your trip around the system, whereas the other one catch the ba seems to be more focused on giving you real time updates. I guess I'll have to see once there if I need any app at all.

Thanks again for the quick responses and help. If any of you do end up buying catch the ba, please let me know what your thoughts are.

You all have a great week end.
