    Tobin Bridge Relocation/Replacement

    We shall see what solutions are proposed, but I’m guessing there will have to be a bridge that is built very close to it while the Tobin remains active. Maybe some sort of open tower like the zakim that goes around the bridge? Whatever’s decided on will be challenging, talking Big Dig level...

    Tobin Bridge Relocation/Replacement

    I think what we’re most likely to see is a bridge built directly adjacent to the Tobin, maybe lanes on either side. Then the existing Tobin alignment will be reserved for bus lanes (hopefully with provisions for heavier rail) which will be built after the new lanes are active. It may be...

    Green Line Reconfiguration

    Quick sketch and not too much thought into it, but what about using SL Phase 3 planned tunnel under Charles st? You have the room to make a flying junction on the Central Subway with the PO sq provisions. Then you avoid the Back-Bay - Bay Village subway S/O Van for the map, one of my favorites

    I-90 Interchange Improvement Project & West Station | Allston

    What buses will be using this entryway? Are we talking about rerouting the 66? If there's a new bus line, I could see one originating from Kenmore and travelling down Comm ave to Lower Allston. I would think the Malvern crossing would be sufficient for that. I don't see West Station being a huge...

    MBTA Construction Projects

    I wonder if the addition of this entrance has anything to do with the Storrow drive reconfiguration/new ME&E garage proposal. I haven’t heard much publicly on this project since ‘21 but I imagine this and Red/Blue would be closely coordinated...

    Other People's Rail: Amtrak, commuter rail, rapid transit news & views outside New England

    It sounds like these trains are just based off the Alstom Adessia platform (a European EMU, also closely related to the Aventra, the train used on London Overground/Elizabeth Line). ConnDOT said they'll be used on the Harford Line and New Haven Line branches (Danbury, Waterbury, and New Canaan...

    Portland Passenger Rail

    This thread doesn't see very much action but I thought this would be noteworthy: https://www.pressherald.com/2023/08/07/amtrak-downeaster-ridership-rebounds/ Hopefully a sign of good things to come!

    General MBTA Topics (Multi Modal, Budget, MassDOT)

    I would venture to guess that the overall maintenance assumption of a structure is underestimated compared to older structures that were mostly overbuilt. When a structure has been “value engineered” as mentioned above, it usually means less use of a material, not always just shoddy...

    Other People's Rail: Amtrak, commuter rail, rapid transit news & views outside New England

    During this comparison, it can't be ignored that the seaport came to be because of the TWT extension of i-90. Considering the attitudes of the time, I think we're lucky to even have the Transitway in existence as a piece of infrastructure. The European examples seem to revolve around a major...

    General MBTA Topics (Multi Modal, Budget, MassDOT)

    Commuter rail ridership counts are usually done by hand, with counters at station entrances. It might not be an exact science but that could be done on GLX to at least get anecdotal numbers. You could also get a ballpark on fare evaders.

    Historic Portland Discussion

    I recall reading, probably on this forum, that Franklin was widened the way it is to accommodate Cumberland/Congress underpasses. I’m fairly confident Portland won’t be needing that sort of infrastructure anytime soon. Using a part of the median as bus lanes would be an intriguing option...

    Green Line Extension to Medford & Union Sq

    The garage can't be imploded due to the tunnels and infrastructure underneath. I don't think you can plan a transit extension around one garage demolition, it's just unfortunate timing. As excruciating as it is, the only way to take down that garage is a piece by piece dissection as is...

    Regional Rail (RUR) & North-South Rail Link (NSRL)

    Are those rendering BEMU’s or EMU’s? I’d be surprised to hear that Siemens is working on a battery locomotive. And I thought the Stadler rendering was part of the EMU RFI?

    Crazy Transit Pitches

    I think the real driver for a full RLX would be Massport using Hanscom as an auxiliary airport to Logan for commercial flights, but don't tell anyone in Lexington that :oops:

    Crazy Transit Pitches

    I think the only thing you'd need to ensure it would work is the wheel profile, which is different for LRT and HRT based on performance requirements. The LRT may be restricted in speed, which would probably be okay for non-revenue service. I'm unsure of regulatory requirements for running LRT on...

    Silver Line at 21: Do people like it now?

    I think the best case would be to have battery electric buses capable of in-motion charging in the tunnel, as discusses on this forum before. It's basically a trolley-bus with batteries. I guess the BEB's used on the silver line for the pilot program struggled with the range required for SL3. I...

    Silver Line at 21: Do people like it now?

    The "blades" that the ropes are tied to are actually called cleats. Exactly the same thing you would use to tie a boat to.

    Route 1 Project - Malden, Revere, Saugus

    All of those cities except Danvers are accessible by a train from North Station. But I get your point that the last mile is difficult. The goal for many transit advocates is to reorient land use policies to favor living and working in transit accessible areas. Not continue the status quo of...

    Regional Rail (RUR) & North-South Rail Link (NSRL)

    The NSRL really wouldn't be able to work if it was built piecemeal. The approach to SS under coming from Back Bay requires a tunnel boring machine for a large portion of it. That would be too difficult to remove downtown and it can only travel in one direction (so reversing out the way it came...
