More space for seats and a less jolty ride. Plus higher speed is more important than high acceleration on longer distance trains

The T is obviously different from Tokyo Metro or it would be nonsensical to talk about making it more like Tokyo Metro
-
"If we were building the Tube now we'd probably build it like Crossrail" means there is a convergence in form between urban and suburban rail, but that this wasn't known at the time the former was built. Now that we DO know, we build the latter, & retrofit the former accordingly
-
I suspect it's too difficult to retrofit the Tube, and particularly the Paris Métro. Or the T for that matter.
-
Overnight? Of course. Over a long enough time span? Nonsense!
-
The only question is how long that time span would be. Gradual changes and incremental improvements + time = radical changes and dramatic improvements
-
I trust, of course, that you wouldn't advocate making NO effort to improve the Tube/T/etc?
-
Of course not. But things like platform extensions or tunnel reboring can be very difficult.
-
Right! So we either do them slowly, or we don't do them at all. I'm advocating the former.

You can't really get a cheap Boston Crossrail by sticking MBTA commuter trains in T tunnels. Nor IMHO would you want to. And nor would you want to go to Providence on a subway like train.
-
You would certainly want subway-like *frequencies* to go to Providence, though, and what about the vast majority of commuter rail stops which are much closer to Boston than that?
-
Obviously you can't stick *current* commuter trains into the tunnels, which is why I said at the outset that this sort of improvement involves new commuter trains.
-
Depends what you mean by "subway like frequencies". Certainly not 36 an hour!
-
To the best of my knowledge there are no frequencies that high anywhere on the T...even in Tokyo: Odakyu only recently moved up to 36 an hour (from 24) and that's on a 4-track line! But the current frequency is around 1 or 2 an hour, and there's a lot of room between 1 and 36
-
The Victoria line is now 36 (at peak), I believe. With two tracks.
-
The busiest subway line in Tokyo (Marunouchi Line) peaks at 33 trains per hour iirc. I don't know of any that go higher than that, but I may be forgetting something. Moscow Metro tops out at 40 per hour (90 second headways)
-
Admittedly these are short (133 metres) and small trains. Not full size as in Tokyo.
