There already exists a Train Driver Mod made by headscript but this mod was a little bit unrealistic because the train accelerates too fast and also stops to fast. With this mod it is more realistic. There is also a handbrake function added. Pressing the X-Button will stop the train completely.
NOTE: DO NOT SAVE WHILE IN THE TRAIN!
– Copy the contents of the folder 3f111b-LUA_SDK and Enhanced Train Driver Mod folder to your GTA V Main
W – Accelerate (tap to accelerate slowly)
S – Decrease speed (tap to decrease speed slowly)
E – Horn
F – Enter/Leave the train (make sure you aren’t very close when you enter it)
X – Handbrake (use this to stop the train completely)
