I did ad hoc high speed line to airport comparisons in
Railways, energy, CO2 - Part 2
, too, with much more CO2 for HSR. In that calculation, based on the Frankfurt-Cologne line in Germany (which has slab track), most of the concrete was in tunnel linings, but long bridges (like on Asian lines) would exceed slab track similarly.

That looks great. One thing to note with steel is that unlike concrete, it can be very efficiently recycled, using little extra CO2. I wonder if this means we should consider building more with steel and less with concrete (or use steel coated in cement for weather resistance - a few cms of low water/cement mortar can protect steel for hundreds of years.
