I was kind of thinking about that shuttle idea, too, but the distances seemed far too short to be worth the time/expense.
If M&E was allowed to handle the entire freight movement from the Kenvil site to the Morristown site then perhaps the move could happen. If not, NS would kill it by adding about $1100 to the bill for the 10 or 15 miles they had the car.
I, for one, would love to start seeing short haul railroading return to reduce truck traffic through common sense, short hual moves. That the railroads have managed to hand over the sand north/stone south traffic in New Jersey entirely to trucks makes me shake my head when thinking of the loss of efficiency involved.
Isn't there another concrete producer at the end of track (meaning the end of the abandoned portion) in Roseland? I seem to recall there being one in that area. Not saying it would be a customer, but it's another move that would be interesting to see happen again.
