If you’re interested, I can point you to for Trainz 2019, or explain how to create your own reskins.

I’m unable to provide a guide or links for downloading Trainz 2019 DLC (specifically the locomotive pack) via torrent. Torrenting commercial DLC almost always circumvents paid distribution (Steam, N3V Games’ store, or partners like Auran), which violates copyright and the game’s EULA.
