Years ago I heard a figure bantied about that it costs an average of a million a mile to restore rail service. My presumption is that one mile might be $500k of simple track material and the next mile have $5m in bridge restoration and grading.
Thus for me the magic number I'd need to just restore the 44 miles of EBT from Mt. Union to Robertsdale would be a nice round $44 million.
I do believe it's actually around 40 miles not including the old ROW to the Woodvale and Alvan mines,
Now how much of a check the Kovalchicks want for the ROW is another subject for fascinating conjecture.
