When will the poles be installed for the overhead power lines?
I prefer them too. I'm guessing they've gotten rare because they look labor intensive (having to lay and backfill course-by-course). Is that so?
Last. There's going to be big poles on the center-median fence between GL & CR sides so they have consolidated infrastructure to someday hang electrification bracket arms over the CR side from the same poles.
That... sounds like the T is better at future proofing and provisioning than I gave it credit for, given that CR electrification was barely a glimmer back whenever (1990-2017) that spec was developed. I could have sworn that the 2017 contract called for twin side poles, but that's a easy, affordable and sensible change if made early enough.
This begs the question though: obviously, 13.8kV/600v is a completely different beast than Amtrak's 25kV system (which I assume the T will build to for simplicity's sake), so I doubt that any of the TPSS sites were spec'ed to be readily suitable to accept a paralleling station, for all that they seem over sized to me. It isn't hugely important, as the between Red Bridge and CR and GL VMFs, there's enough land to build something for north-side terminal electrification.
Spring, Summer, Fall seems like a win. What will it look like in mid-winter?Awesome, thank you. Reading the site it says the planted wall also has the benefit of graffiti control, along with better sound deadening, looks etc. I didnt even think about the graffiti aspect, thats awesome!
I personally cant stand most graffiti that looks like a 3rd grader scribbed their name on a wall, this is a huge benefit that it prevents this. Not only is there no graffiti, but its green too, talk about best of both worlds. They should definitely use more of these.

The planter walls do appear to have two advantages: varied texture & angle.... better sound deadening
From Mass DOTWhen trolleys crossing the Lechmere viaduct had to stop for boats
The opening of the Lechmere viaduct across the mouth of the Charles in 1912 meant a dramatic reduction in the time it took trolleys to cross the river, from ten down to just three minutes - except when a cargo schooner came through and the trolleys had to stop for the viaduct's drawbridge to go...www.universalhub.com

Demolition activities will occur from 7 a.m. to 7 p.m. followed by clean-up activities from 7 p.m. to 10 p.m. Less disruptive activities such as work zone preparation and breaking down traffic control items will take place overnight.
Very much so. Nearly all the newbuild is the Drill-Hbeam-Panels styleAren't those precast planter walls the old retaining walls?
