Hi, I really am amazed at how all of the sudden, trains are really becoming more and more popular in Beamng! I really like your SD-40, my family used to work on the same ones when they worked for the railroad. One question, do you think that you could make skins for other railways? Southern Pacific has some sentimental value and would fit right in with the other locomotives soon to be out on the forums. In fact, the SD-40, could at one point be found on almost any Class 1 railroad and now are becoming some of the backbones of Class 2 railroads. Nearly, if not all paint schemes would work on this. It also does fit in quite well with the Rio Grande F7, considering that it and the SD45 were some of it's successors. Anyways, keep up the good work and can't wait for this to be ready to download!
