I work for the MTA and we only have the Marc train system
from baltimore to DC.The subway runs only on the westside
of baltimore and the Light Rail also.You can water taxi
from the Harbor to fells point and few other locations.
Yellow transportation taxi cabs are always at the Inner
Harbor East.The light rail will bring you from BWI airport
to baltimore.You can always ride our New Flyer transit
buses around baltimore.I hope you don,t get one the old buses to ride
almost as ugly as DC transit
Good Luck and enjoy Baltimore
BTW the Orioles suck!
