This is the GTA 5 Freight Train mod by SergeDV. It was converted to Android by RIZKY GAME. I've imported the textures with Txd F*cker. Now you don't need a PC anymore to install this mod.
How to install:
1. Replace freiflat.dff and freight.dff with Img Tool Android
2. Move gta3 to Android/data/com.rockstargames.gtasa/files/texdb
3. Move carcols.dat to Android/data/com.rockstargames.gtasa/files/data
Thanks RIZKY for converting this mod to Android!
