First off, I must say that that is a nice town design. The buildings are decent represenations of those found across the American Old West.
Secondly, I find it interesting that you base the Brick Railways System out of Springfield, Missouri. There was a real railroad based out of Springfield called the St. Louis & San Francisco Railway. It was better known as the Frisco though.
I also thought I would give you a suggestion. You might wish to add a trackside baywindow to your depot designs in the future. I've rode many trains across this country and like 90% of old railroad depots and stations featured baywindow.
Good work! I hope you enjoy your layout.
