Station 51
The fire station used for the TV show EMERGENCY! was and still is a real firehouse. Station 127 is located in the City of Carson, which is located in the southern part of Los Angeles County.
The real Station 51 was established in 1994 as a homage to the TV series and is located on the back lot of Universal Studios in Hollywood, CA where much of the series was filmed.
There is a very small gift shop at Station 51, but the station itself is not accessible to the public (you do get to drive by it on the studio tram tour). Now you can own the same official station gear that the firefighters at Station 51 wear and offer in their gift shop!
