Vic,
I live 1 mile from that line, which also happens to be where the change from the original route takes place. Since some of the original right of way had been graded, but no bridges were started the abandoned line can be seen, hit and miss to just north of the IU football Stadium.
Enough has been written, here and there, that I put all of the pieces together. That is except for the actual location of the tunnel east of Stanford that was actually started. I could not figure that one out. One day Steve Stafford and I met with Clay Stuckey at Bedford and exchanged a lot of information. One of Clay's finds was the actual location of that abandoned tunnel. I checked it out and that solved the mystery. Later I found written evidence that supported all of the pieces and then fellows like John Butler also researched it and comfirmed it. So, it was a community effort. The surprise I think to us MONON researchers was the planned at grade crossing in downtown Bloomington, that never materialized due to the change of the Indianapolis Southern's mainline.
