Decision Time

Given all the parameters and the material the decision is to follow the path of the City Point lines of the USMRR.  Going this direction will engender certain compromises, but far fewer that if I try to model a more traditional full division of even a Civil War era railroad.  The length of the line at a maximum of 19 miles from one end to the other makes this more doable than the other options.  High density of traffic is another plus for this prototype.  The next step will be to list the materials I already have in my possession and track down additional sources.
