And, yes, one note about vehicle speed script included in this mod...
I tried it on large map with train line which going almost diagonal from one side of map to another... train was only 7% faster with this mod enabled.
Why? Because this script don't change speed limits of roads or railways...
It only set maximum speed of vehicles. So, train or truck can drive faster only if railway or road allowing that... if you have old type railway with max. speed of 120 km/h - your train will still drive max. 120 km/h.
Same thing is with trucks... they don't drive through city with 130 km/h...
Only real advatage of this mod/hack/cheat or whatever you wanna name it, is: vehicles are faster on start moving and they are only little faster in drive... all other settings like tractive effort, weight of vehicles and speed limit of road/railway still reducing speed of vehicles.
