I would be. There's not additional room through Quincy for that and even if there was I doubt doubling an existing rail service is the best use case when those trainsets could go towards expanding services like the Keystone, Pennsylvanian, Piedmont, Wolverine, or Borealis.

If Amsterdam and Rotterdam can build metros when the city is below sea level I have no doubt it's possible. Whether it's practical in the context is a different question and when the Grand Junction alignment is (mostly) available I think the answer is no.

The base map is imported into Illustrator from QGIS and then I adjusted the colors on each layer to make it look just right. There's still a little more I want to do with it but it's pretty good. And as you can probably imagine the lines and stations themselves are not complicated. Here's the...

No idea is ever original is it

... wouldn't that need an act of Congress?

I don't think it's that crazy it's taken this long. The derailment was June 2019, it took 3 months for regular service to be restored so stopping there and giving everyone a break from shuttle trains and slow zones was probably warranted. Of course soon enough it was March 2020 and COVID...

Unfortunately enforcement is near non-existent though so 🤷‍♂️

NL laws are very clear on this. If it can go faster than 5km/h without pedaling it's a moped, not a bike.

Which it does by using trains that have as many doors as the Orange or Red Lines, and Spanish solution platforms at all the interchange stations. Unless we plan on replicating that with the NSRL you're not getting those numbers with regular island platforms and a mixed fleet of mainly commuter...

We do have international examples to compare against too. The RER is probably the best example, last I heard RER A is the busiest double-track rail line in Europe and is probably the world leader in trying to cram as much capacity as possible out of Bi-Level intercity rolling stock used as metro...

At 35 TPH that assumes ~3.5 minute headways. 120 minutes (2x60) ÷ 3.5 = ~34.2, rounding up to 35. Looking back I agree that 3x is probably too much for Amtrak, 2x is probably better. But I don't think it actually changes the conclusion, to be honest.

With an expanded CR network the numbers start to get tighter. I'd say ~35TPH is a fair estimate for max sustainable capacity, and I'll estimate that Amtrak trains count triple due to longer dwell times. Line TPH Newburyport/Rockport/Beverly 6-8 (2-3/2-3/2) Lowell+NH 4+2...

25MPH pedal assist is crazy. Here in NL the limit is 25 km/h (~15MPH) and even that feels dangerously fast at times.

So, how much would all this cost? Let's use $1bn per mile for subway portions and $600m per mile for elevated/surface. This is in line with construction costs in SF/LA, Honolulu, and Vancouver. Segment Length Cost Everett Subway (Linden-Sweetser Circle) 2.8 miles $2.8bn Everett-Inner Belt...

When compliance looks like, or at least can look like, a relatively small area that's zoned to allow duplexes, I'm not exactly overflowing with sympathy for any town really. You don't get to run a town like a gated community in a white flight suburb of Atlanta.

Wow, what a throwback. Of course. But engineers 100 years ago were not bumbling idiots and so we can have some level of confidence that the infrastructure was designed as they said it was. That's the difference between going into a study where the result seems like a 50/50, and one where the...

No, this is my 'Aqua Line' idea that I've posted several times before. I'm just finally getting around to making a nicer map/presentation for it.

An Everett Subway, but a fancy map
