Will it be a 3 track crossing (Cape Flyer, Dinner Train, & Propane?)Project will finish with a full do-over of the MA 28 grade crossing and traffic signals.
Looks like it will be a four-track crossing at Route 28. Details are in the attached PDFs on the commbuys website: https://www.commbuys.com/bso/extern...100-0T100-49904&external=true&parentUrl=close
The state also has plans in the works to rebuild portions of Yarmouth Road, including the intersection with Route 28, as well as (I believe) a bike path parallel to Yarmouth Road. I assume the crossing work is being done with these other projects in mind.
They've been working on the railroad, all the livelong day
After one crew spent last night on equipment that gnawed away the old Needham Line bridge over Robert Street in Roslindale Square, another crew came in this morning to get the new bridge into place and ready for trains on Monday. Read more.www.universalhub.com
Robert St. bridge @ Roslindale Station on the Needham Line is being rapid-replaced throughout this weekend. New decking is now in-place.
Will the MBTA continue to deploy such rapid replacements across the system when bridges need to be replaced?
Between 2020 and 2023, we'll replace the following bridges, with construction expected to start in this order:
Why These Bridges Are Part of the Same Project
- Bacon Street Bridge – Framingham/Worcester Line
- Intervale Road Bridge – Framingham/Worcester Line
- High Line Bridge – Lowell Line
- Parker Street Bridge – Haverhill Line
- Lynn Fells Parkway Bridge – Haverhill Line
- Commercial Street Bridge – Newburyport/Rockport Line
We’re using a design-build contracting method for the 6 bridge replacements that are part of the MBTA Rail Bridge Replacement Project, which will:
- Reduce design and construction time
- Improve communication between the contractor and designer
- Provide a single point of responsibility for both the design and construction.
- Promote collaboration between engineers, the contractor, and MBTA staff
High Line (a.k.a. Lowell Line over Boston Engine Terminal) is a vertical clearance bottleneck for freights, and would prevent most of the backside of BET from ever being electrified for wyeing moves if it weren't raised. Has to be redone adjacent on new/taller abutments rather than rehabbed/re-decked in-situ so they can add some height, and do as a different abutment configuration that can cup a thinner deck not nearly as chunky on the underside as the current one. See Street View: it's a real shorty.Interesting how the High Line is the only one which is not being replaced in-place. Instead, it’s shifting northward.

Also, I'd point to the inciteful comment on the article you shared regarding trains going over at slow speeds for the first few days.
1927. In prep for the 1928-replacement North Station, B&M did a large reconfiguration of the approaches. The NH Main used to continue going straight on the path of the current GLX main and former Pan Am Yard 8, then wrap alongside the Fitchburg Line into the drawbridges rather than flying over everything and merging in with the Eastern/Western Routes. It was likely separated to keep the pax trains out of freight yard limits. Since Innerbelt Rd. didn't exist back then and everything in sight was B&M train yard property with widely scattered buildings, they just dumped some embankment dirt and did up the High Line on-the-quick.This reminds me of something I've been wondering: when was the High Line built? I assume it was to separate passenger trains headed for North Station so they didn't have to go through the freight yards.
Do you think given (presumably) much more limited current freight volumes that reversion to the pre-1928 routing would ever happen? Removal of that length of track would open up that entire swath for redevelopment, although you've still got what looks like an industrial access track along New Washington.1927.

If they were thinking of that, they would've done it already as part of GLX design because that would've been the time to do it. But they didn't...the GLX land is spoken-for...and they can't even take the marbles out of their mouth on whether a single track of freight-idling wraparound track will ever be reinstated so it's probably overestimating by a lot the intrepidness of the planners to have thought of that as a consideration in the first place. That ship has almost certainly sailed. Arguably it sailed in 2008 when the T and Pan Am consumated their land swaps all throughout here for the project.Do you think given (presumably) much more limited current freight volumes that reversion to the pre-1928 routing would ever happen?
