What??? There's no rule against using crossovers for meets/overtakes, no FRA frowny-face. It's done all day every day across the country. And it's completely, totally safe with the signal system they have.If you are going one way, sure. But you need trains to be able to go back. I was under the impression that the FRA is strict about flipping the switch to switch tracks. Like the pushback on the Newton stops.
And what pushback on the Newton stops? They clog up traffic as single-side platforms, and the T got blasted for trying to design the replacement Auburndale as yet another single-side platform (on the *worse* side for traffic management, no less). It wasn't some arcane rule or federal oversight that upended those plans; it was the T presenting a transparently rock-stupid design and getting called out on it by the public.
The Worcester Line needs a higher-density signal system and more sets of crossovers to mix bi-directional :15 local service with express overtakes, but it can indeed be done on 2 tracks so long as the stations all have 2-track platforms. The T's own in-house Rail Vision explicitly proposes exactly that here.
