i have nooo idea how trains work so maybe someone can explain…a signal problem underground, from the sounds of it, was preventing the tracks from switching.

but that would mean the tracks were just leading to the wrong place, yeah? so how and why is it considered BETTER to evacuate trains and make people walk back to copley in the tunnel, rather than just continuing any “stuck” trains into the next station, even if they ended up on the wrong side of the platform, and letting passengers out there?
