The Freight Train is a diesel locomotive from Grand Theft Auto V and GTA Online that is due to appear in Grand Theft Auto VI. An official screenshot of Mount Kalaga National Park shows a blue-and-yellow, Boxtrax-liveried unit crossing a railroad bridge in a color scheme reminiscent of Florida operators like The Bay Line and CSX, and the four-axle road switcher is closely based on an EMD design.
