The GLX is going to open for use and the noise walls will still be incomplete.
Rapid transit dimensions vs. high-and-wide freight clearance route.Interesting how the Green Line tracks (in opposing directions) are a lot closer together than the CR tracks.
why would they be replacing the rail on the CR side after just relocating those tracks?
Dont know much about rail, are the current rails temporary?
Is there to be a connection to the national rail network at Brickbottom, then? I can't imagine driving a rail train of any length through the Central Subway.Or Brickbottom. Lots and lots of flatbed deliveries, though theoretically a shove up Riverside Jct. from the Worcester Line can do the job. In most cases replacement rapid transit welded rail comes in max 200 ft. ribbon chunks and more onsite welding is required for the installation to net an 800 ft. length. You simply can't turn a rail train longer than 200 through some of the curves.
The freight line railroad runs alongside the Green Line all along the new route. No need for a connection.Is there to be a connection to the national rail network at Brickbottom, then? I can't imagine driving a rail train of any length through the Central Subway.
so that, where needed, the ballast can fall into place between the ties via gravity (and mechanical shaking). After enough has fallen/shaken/tamped between the ties, they sweep off the extra.Why do they cover new line tracks with gravel and then removed most of it
F-line indicated they'd have to run it up the actual Green Line tracks, because of the fence in between, and that they could do so at Brickbottom.The freight line railroad runs alongside the Green Line all along the new route. No need for a connection.

They're also still running heavy construction trucks over the ROW, so need a more level gravel surface for time being.so that, where needed, the ballast can fall into place between the ties via gravity (and mechanical shaking).
