Safeco Field has a unique retractable roof that only acts as an "umbrella" for the stands and field rather than forming a complete climate-controlled enclosure, as is the case with retractable roofs at Rogers Centre, Miller Park, Chase Field, and Minute Maid Park.
It is one of the few Major League ballparks to feature a manually operated scoreboard.
The stadium adjoins a working railroad yard which can be seen from the balcony behind the center field seats. Trains traveling through the yard sound their horns, which can be heard in the stadium and during broadcasts. Before the 2001 All-Star game Major League Baseball requested that trains traveling through the yard during the game not sound their horns; the Burlington Northern and Santa Fe Railway refused, citing safety concerns and Federal regulations.
