Re: North Station, Charles River Draw, & Tower A

$100 million is the design and construction cost. And relocating a major station more than a quarter mile further away from its transit links just to get out of rebuilding a bridge strikes me as......

Re: General MBTA Discussion Thread

That's the one that kind of threw me... like, how do you even route that? I've heard talk here about a westerly Blue Line extension under Storrow, but this is a new thing altogether.

Re: South Bank Bridge Project | West End

Not quite; they'd also have to build a bridge across the river. This is, I believe, planned for when they replace the railroad drawbridges.

Re: North-South Rail Link

Not really. Without the NSRL he'd still have to transfer between North and South Stations. With it he can change trains at South Station, which is much faster and easier.

Re: North-South Rail Link

As far as I can tell the Boring Company is a used TBM that Musk picked up on Craigslist somewhere and a crew to run it. Unlike space transportation or electric cars, tunnel digging seems to be a...

Re: North-South Rail Link

Ah. For some reason I get those two confused. :-) Actually calls for two two-track tunnels with the tracks on two levels.

Re: North-South Rail Link

I read an article, probably by Ari Osfevit but I can't find it at the moment, advocating digging the NSRL with a large-diameter TBM, large enough for 2 levels of 4 tracks each and station platforms...

Re: North-South Rail Link

The report you linked to says nothing about the CA/T tunnel having been excavated and backfilled for the NSRL. It's also from 1997, which was early in the Big Dig construction process. Mind you, they...

Re: Commonwealth Avenue Improvement Project

Yes, in bike facility design there's a tension between making something you can go fast on and something that's slower but facilitates broader use. As an experienced urban cyclist who likes to ride...

Re: North-South Rail Link

I want a source for that. It makes no sense at all to dig further than you need to and fill it back up with dirt. They'd have to dig it out anyway to build the NSRL, so what good would it do?

And...

Re: North-South Rail Link

I don't think that's true: the slurry walls go down to bedrock, but I'd be surprised if they dug any deeper than they had to to build the road tunnel.

Re: TransitMatters Regional Rail Plan

You're still forgetting the space taken up by the motors, which aren't small. If you've ever looked at a powered truck without a railcar on it, there is no space left.

Re: North Washington St Bridge

Charlestown is accessible from basically 3 points: Sullivan Square, the Gilmore Bridge and the North Washington St Bridge. (Well, and the Rte 1/I/93 ramps.) I can easily see where shutting down one...

Re: TransitMatters Regional Rail Plan

Problem with putting the batteries in the trucks is that a battery pack that can power a commuter rail coach any reasonable distance is going to be kind of big, and powered trucks don't have a whole...

Re: TransitMatters Regional Rail Plan

The trucks on commuter rail coaches are not powered trucks, and adding motors to trucks that were not designed to be powered doesn't strike me as remotely low-effort. You'd be much better served to...
