You can load them by conveyor I do it all the time on my coal mine map I have setup thats how I load my rail cars if I don't choose to use the mining loader that day
Any chance we'll ever see a rock island railroad skin for the old alco such a beautiful paint scheme and loved rail line in the rail fan community or the famous orange and black livery worn by the genesse and wyoming shortline?
Jweezy Idk if its a known issue but I noticed in your railcar files one of the boxcars in the store has an issue loading and appearing in the store when you select it
