Line-of-sight is obviously subject to human error, but I think in other equivalent installs of CBTC on subway-surface tunnels (SF and Philly) capacity has actually gone down, in part because no signal system is OK with double-berthing.

It’s very Japanese of you. I’m not sure it’s the best use of funds even with a lot more $ but it’s intriguing

It's very Japanese but also has a long history in old '60s and '70s Boston transit plans. The core problem I see, aside from federal regs, is that the core subway trunks here are relatively low-capacity and will probably fill up with just existing service in the coming years.

It does fit my idea of a Fairmount Line + downtown subway tunnel to Chelsea via Charlestown or East Boston though.
-
Isn't the Blue Line tunnel under the river really narrow with relatively tight curves: it requires short rolling stock as well as narrow el loading gauge cars: running that with high platforms on mainline seems like it would suck badly.

Yes, it presents a real issue for Alex’s through running idea I think.
