High Speed Rail Atlas 2024

Clark to Ham constant tension is probably about to start work soon. The poles are partially complete. Meanwhile, most of that section is actually SAP, like County to Midway, and not original style. Yet only County to Midway is rated for 145 mph (except curves) and all other SAP sections (there are several others to the south) max out at 135 mph. I have no idea why.

See OpenRailwayMap for speeds.
