Hartsfield-Jackson International Airport wants to give the Plane Train a roughly $9 million upgrade.
Why it matters: The Atlanta airport's workhorse transit system carries 250,000 passengers a day and helps pace the never-ending flow of people at the world's busiest airport.
Details: Officials are asking the Atlanta City Council to approve the $8.6 million purchase of 29 new vehicles.
The vehicles' interior will change but the layout will essentially be the same, an airport spokesperson tells Axios.
Intrigue: The Plane Train doesn't have steel wheels like a choo choo. It uses rubber tire technology on a fixed track, so think more "bus" than "light rail."
