Boston transit priorities in no particular order: - Stations, vehicles, etc must be CLEAN and in good repair - Lighter trains on Red, Orange, Blue lines - Infrastructure in good repair - Dedicated bus lanes + transit-favoring traffic lights - Commuter rail to subway standards
"Commuter rail" in Tokyo is more or less indistinguishable from subways--they employ the same kinds of trains and even offer through service from commuter to subway lines. I talk about "commuter rail" so people know what I mean, but the term I prefer is "suburban rail"

Something I've not seen in Europe. We have the RER concept, where commuter trains run through the centre in separate tunnels, but not commuter trains on subway tracks. Not any more anyway. (We used to - the District line once had trains to Southend.)

The RER concept is pretty much the same concept
-
It's a bit different because you have much bigger tunnels, longer platforms and fewer and further between stations. And less frequent trains (RER C in Paris is particularly bad for that).
-
Differences in tunnel dimensions or platform length can easily exist *within* a subway network (Tokyo's has 3 different gauges and at least 3 different power sources!). Wider station spacing is the same from rider's perspective as skip-stop services on more dense lines...
-
...and low frequency is just a deficiency--nobody benefits from that. Differences between commuter rail and subways are generally arbitrary as they are both trying to accomplish the same goal: moving large numbers of people in constrained spaces. Same goal = convergent evolution
-
I think there's a continuum though. The further I'm going, the more I want a seat, a toilet, a table, a power socket, a drinks trolley etc.

Sure--and why shouldn't a train with all those features (assuming compatible infrastructure!) run through a subway tunnel?pic.twitter.com/a6nFTnOUwX

In theory, nothing. In practice they're usually too different to run without an unacceptable capacity loss.
