ATS - Spawn Fix for Improved Trains Mod (1.40.x)

Citation from SCS forum about Improved Trains mod:
“Do the trains spawn in and out of the scene correctly now?
This is the main reason I stopped using it.
It blinks out of the scene and breaks immersion for me.”
WITH THIS FIX ALL IN-OUT TRAINS SPAWN OPERATIONS ON THE SCENE WILL BE CORRECTLY!
PLEASE RESTORE DOWNED TRAFFIC DENSITY, BY OTHER MODS INCREASING TRAFFIC DENSITY.
DO NOT USE “g_traffic” COMMANDS. THESE COMMANDS MAKE TRAINS UNBEARABLE FREQUENT
work in both SCS games, checked in 1.40
Fix must be placed in highest priority above the Improved trains mod, his addons and any traffic density mods.
Enjoy it and Have Fun with immersion!
Thanks Cipinho and Todor Alin for information about hidden settings prism3d game engine
