The Train is a vehicle featured in "Heartland". While it is undrivable, it plays a key part in the plot, along with being frequently seen driving around the map. The train consists of the following units:
- Locomotive - The Locomotive is based on an EMD GP40 painted in CSX colors. However, instead of the livery reading "CSX", it reads "AV", standing for "Allegheny Valley".
- Boxcar - The boxcar comes in two liveries, the default "Freight" boxcar from GTA 5, and Northern
- Tanker - The tanker is painted flat black in a Prillex livery.
