From Halopedia, the Halo wiki
One point of access is through a reinforced emergency door from Sector B - this leads to the parking facilities; another point of access is through a tambour door adjacent to the main station entrance. Liwitoni Station has eight ticket booths and three phones, as well as five of what appear to be closed circuit televisions.
Liwitoni Station, along with every other MagLev station, was closed following the Covenant invasion during the Battle of Earth. The maglev rail system was one of the Covenant's first targets during the battle.
