Just a minor thing I observed: If you select the mod in the game's mods manager, the description next to the thumbnail says: "Use the new Black Fluid Tank Wagon that gives you the double of space". That's obviously wrong, it should be something like: "Use the new Black Fluid Tank Wagon that gives you three times the space of a normal one". Guess you just changed the text from Double Cargo Wagon without adjusting the figures. :-)
