Thank you for your interest in Houston TranStar. Fill out the form below to submit an inquiry about a tour. Tours are normally available on Tuesdays and Thursdays at 10 a.m. or 2 p.m.. Currently, we are in the process of building reconstruction so we have changed the tour hours to weekends or weekdays after 5 p.m.. There is no cost for the one-hour tour, but we require a minimum of 10 visitors, ages 12 years or older.
