Under South Street, at least where it intersects Essex St. This would suggest to me that any alignment using Lincoln St, Hudson St, etc would still encounter this problem. The only way around it would be a surface connector. The planners of SL Phase 3 of course knew this, and seemed to be fine...

In 2022 per the ESPR it was between 11.5% and 18.5% depending on what you count as a "private bus." Limo/van services accounted for 4.3% and courtesy shuttles were 2.5%, I'm not sure if they should be included or excluded. If you really wanted to fudge the numbers you could argue that people...

I've gone back for another look and I think I have at least a rough estimate. The main limiting factor for gradient on the South Station incline is the New East Side Interceptor sewer, around 25ft below the surface. The tunnels need to rise around 16-17 feet to meet the Transitway at ~8-9ft...

Would anyone here know where I could find details about the proposed grades for the "Core segment" of SL Phase III? I think the Essex St alignment was settled on in 2002ish, anything from then? The 2005 EIS has loads of detail about the portals but relatively little about the core section. The...

It really needs to be at least a timed transfer at a minimum. If the trolley loop goes, as is the plan I believe, it should be a pretty straightforward overpass with elevators or ramps.

Restating my thoughts on this, for the Nth time: Capen St: Needs a path to Mattapan Station but assuming that's done, the stop can be eliminated. Valley Rd: Safe to be eliminated with no mitigations. If Milton feels strongly to the contrary they can foot the bill, same for Capen St. Central...

I've put off finishing my revised CR redesign for a while, probably time to get around to it. I should just have the zones left to do.

We know from SL Phase 3 that it is. While that part does require some steeper grades to hook into the Transitway, the EIS doesn't raise any concerns about that part, which suggests that part of the project was pretty solid in terms of engineering, it's only once you start trying to connect it to...

I mean it's just my most recent fantasy map but very lightly modified and with everything that's not GLRC cut out. I'd not really consider either of them to be great pinnacles of design, if you want that I'm still very proud of my current map redesign.

I'm reasonably confident at this point that the Essex St alignment is the easiest connection between the Boylston St Subway and South Station. There is a clear spot for a flying junction west of Charles St, and there shouldn't be any unreasonable grades. I also think if you're fine severing the...

wait what you can't just say that and not elaborate further

Partially demolished for the new fare lobby unfortunately, so not really in a position to be reused. The portals are also in really terrible places, one on Foundry St and one filled in under Dorchester Ave, not on Broadway. Reusing it is probably more trouble than it's worth. At that point it...

Notes from the Hi-Rail Tunnel Meeting tonight: The attendees tonight had a significantly more "NIMBY" character than the previous meeting. To some of the people present it doesn't matter if the construction is safe, it just shouldn't happen at all. A common theme was to make it Arlington's...

Perhaps not to risk a derailment like has happened several times now from infrequently used switches. It's also just not really necessary, two trains lets you have a shuttle train every 10 minutes.

Coach station on the edge of town is certainly not a new concept, but as long as the South Station bus terminal and highway connection exist downtown, I don't think there's much reason to relocate them. The bus station is built on top of the tracks, so it's not like there's valuable land being...

And we could also go deeper with the "Why?" for the Nubian trunk in the first place. I don't think the corridor really has a lot of branching opportunities, and even with 12 TPH to Nubian, 12 to Needham/Riverside, and 6 to Hyde Sq or Arborway, that's still within the constraints of a single trunk.

So if you want three trunks you need two extra tracks between Boylston and Washington St, and that pretty much means doing some form of SL Phase 3 as the easiest link between Boylston Inner and Washington St is probably from the west... somehow. Of the portal alternatives: Columbus Ave is in...

I think the Outbound platform switch is feasible. You'd need to modify the flying junction somewhat but it looks at least doable. Inbound I don't think is workable. You'd need trains to make the same sharp curve, but on an incline as part of a flying junction. It also may require some...

Housing affordability in NL is Fucked with a capital F because of the government's insistence on extremely strong rent control. There are some parts I think are good, like capping yearly rent increases and making it very difficult to evict tenants, but so much of the housing stock has rent hard...

You can definitely build a light rail line that can have a few bike racks, but that's very different from building a line primarily based on "bike-up" ridership with large numbers of people hoping to take bikes on board for their trip. They would fill up rather quickly and most people would just...
