as most people that know railroading in north america bethlehem steel mill are some of the best known in the country.
on this map i am posting you start in 1940 when electric on prr was taking off, plus other railroads desiels are hitting the scene. you have to move 100k in steel to win. plenty of close coal mines near the mill to make good cash in the beginning so you can build out of the valley to other side fo the map. the passes are not narrow, and some places wide, but they are not smooth, you have to bull doze and snake your tracks to get through the pass. i colored the mountains differently from the west coast mountains, the ones in the east coast are much more green. so i left the mountains green and sprinkled dry grass on them hoping to get the desired effect.
you need provo installed, and megapack, automod, dk packs, and the advanced lumber pack.
