oes this mean trains going through the underground and grade separated portions of the line will be relegated to travel at the same speed as the trains travelling along the eastern/ at grade portion of the line?
No, they just need to maintain a constant rate of speed in relation to other cars on the line.
You can try this out for yourself with another person: start running from point A, then you walk normally onwards from point B. Have a second person follow 30 seconds later, maintaining the same rate of speed. The only way they would catch up with you is if they continued running past point B.
