Thunderbird Express, Albuquerque Zoo

The Thunderbird Express Zoo Train is different from the Rio Line BioPark Train. The zoo train is contained completely within the zoo and does not connect with the Rio Line although it does shares some track. The station for the zoo train is quite far from from the BioPark train station, on the opposite end of the zoo. Even though the zoo train shares a loop of track with the BioPark train and passes right by the BioPark station, you can't get off there to catch the BioPark train. Very confusing!

The zoo train takes you passed lots of the exhibits and even a few places that you're not likely to see walking around. The zoo train cars are different from the BioPark train, more comfortable in my opinion. If you buy a combo pass when you enter the zoo or the aquarium, you get to visit all parts of the BioPark and ride both trains as much as you wish. It's a lot to do in one day however and I skipped the botanical garden. The sharks in the aquarium were really cool though.
