What do you see as the incompatibility? HSR alignments mostly have gentler curves and grades. If it’s the track speeds then presumably the freight would need to run outside of HSR service hours. If it’s wear and tear on the alignment then that might be a problem all right.The fly in Alstom's oatmeal being.... so long as CP retains a right to run freight, it will be unlikely/impossible to upgrade the line to HSR standard. Especially since the existing traffic is pretty heavily loaded covered hoppers.
