I was recently informed that Malden Center and Malden Centre both exist. They're about 0.6 km / 0.4 mi from each other.
Malden Center is an intermodal transit station, providing bus, subway, and commuter rail connections. Malden Centre, on the other hand, is a hamlet-like thing (a populated place?) about 120 m / 400 ft from the center of Malden.
Worth noting: Malden Center is on Centre Street, while Malden Centre is not.
