If you are risky and want to try something ancient, take a tram from St. Paul street to West Village. The ride is free of charge, and if you are lucky as I was you will here from the driver a lot of stories about restaurants, building and their owners in West Village.
The tram is very small with wood sits and the driver wearing old fashioned suit and with long beard. I had a lot of fun. Sorry, didn't take a pic of the train.
DART is the Public Transportation Department for Dallas. They operate a series of trains that were quite convenient on my last trip to Dallas.
My Experience has been that older cities such as New York and Boston have really well established train systems that take you where you want to go. Not so old cities (like Atlanta) have limited train systems that still need to be developed.
Dallas was a surprise. The system was convenient for us, the trains were clean and the people riding them were friendly. these trains actually ride above ground most of the time and stop for traffic lights.
At $2.50 for an all day pass, it was a good alternative to paying for parking downtown.
The Dart system will take you to many places around Dallas. I took it only once because I travel by car mostly.
If you plan on scooting around Dallas all day. Get a day pass to save you some money. OR if you plan on getting smashed... Dart Rail is the answer once again :)

I took DART for the first time November 22, 2003. They said that JFK event was going to bring many people, so I figured I better not try to park downtown.
