There seems to be an assumption by some that reopenings are relatively cheap compared to building on a new alignment. If the line still has tracks in place and sees occasional traffic then that may be true. But even projects like East-West rail where the line is disused (but not formally closed), reinstatement costs are high. It's not just a case of replacing the old tracks; generally the project involves completely rebuilding the line. The only real asset is the earthworks, and even these usually require major renovation, widening or realigning.
So the question to be asked is whether there is an economic case for building a brand new line over a given route. If the answer is yes then build it. If the answer is marginal but there is an old railway alignment then that may give just enough savings on earthwork construction to make it viable.
