It's been speculated the clover leaf side would be cut in the middle at some point and once the cut is done then the balance toward Frankfort will come up.
As for the IMC portion, NS had the chance to render it done, but at the time the whole lease to Kokomo Grain north of Tipton was in the works. So NS went along, now im.betting they wished they had let the INDOT pull the plug for the overpass on new US31.
YES, Kokomo grain is a BIG shipper, and they have several elevators. Kokomo, Winamac, Amboy, Edinburgh and now RF at Frankton.
I'll sorta walk out on the limb and say the Clover Leaf is in such bad shape even a large outfit like GW would give a healthy pause at rebuilding it. I also wonder what provisions in kokomo for the roadway would or have been made since the overpass Removal.
