Henry I love idea for your map but I think there is an issue with trains. It looks bad when there is only one type of train. This map would be better if there were few variants.
Well of course i agree, but there are only 2 train options, long and short, and i used them both. I decorated them with those stickers, signs and graffiti for some variety - that's the best i could do. Plan is to make 3 more Railyard maps to extend Rail Line Gang quest into a series, but next ones will have fewer trains. This one is the most crowded.
fyi: My grampa was a train engineer and parked many of the old trains in a train museum in my city. When i go there, they don't all look alike, but not too different, and they do all face the same direction.
