Minute Maid Park (formerly Enron Field and Astros Field) is a ballpark in Houston, Texas, that opened in 2000 to house the Houston Astros.
The ballpark was Houston's first retractable-roofed stadium, protecting fans and athletes from Houston's notoriously humid weather as its predecessor, the Astrodome, did, but allowing fans to also enjoy outdoor baseball; something they couldn't do in the Astrodome. The ballpark also features a grass field, compared to the Astrodome's artificial AstroTurf, which was generally disliked by professional baseball players. The largest entrance to the park is inside what was once Houston's Union Station, and the left-field side of the stadium features a train as homage to the site's history. The train moves along a track on top of the length of the exterior wall beyond left field whenever an Astros player hits a home run, or when the Astros win a game. The engine's tender, traditionally used to carry coal, is filled with giant oranges in tribute to Minute Maid's most famous product, orange juice.
