Fair enough, I hadn't realised how difficult it was to control the exact speed of a train at high speed.
But if that's the case then it still seems like the original problem of running two trains right alongside each other, on different tracks, for several minutes while people cross from one to another, and with the consequence of any error being passengers getting sliced in half, would be even harder.
