I feel that most of the cost is for tunneling and the difficulties of working in such a space as a subway system. as for normal railroads, a quick googling shows that the cost is much more conservative, with a 1995 estimate[1] stating about $250,000 per mile to rehabilitate an existing railroad.

Light rail is above ground, often operating alongside street traffic.
