I have just about got the freight car fleet worked out,I have decided to model the era from 1979-the present as if the Milwaukee Road rebuilt the entire Iowa Division with 132 pound rail and was well off fiancially.I have gotten a lot of good feed back about the 2nd plan,it originally was going to be double track back when the Rock Island was going to be included,but the Milwaukee Road will be the only railroad included on the layout.The changes I would like to make to the plan are single track instead of double track and show the yard tracks for the yards,8 tracks for the 1st yard and 6 tracks for the 2nd and 3rd yard.If someone would be willing to redraw the plan with these changes I would greatly appreciate it.The branch line and the industries will stay the same,and I need tracks for the motive power and a caboose track for my cabooses,I plan on having 4-5 bay window cabooses.Any help will be greatly appreciated.Thank You.The radius will still be 30" and the size will be 24'X24',not 25'x25'.Every thing else will remain the same.
