It will if you're short-turning a Reading train while a train to/from Haverhill is anywhere in the vicinity. Reading's way more important than the Wellington siding because of the relatively robust contingent of short-turns on the daily schedule. If Haverhill gets its Bradford-replacement layover (and an end to this interminable double-track project) to finally allow some escalated service levels out to the end of the line, those increases can be supplied by mixing-and-matching more NH Main + Wildcat trains with whatever whatever combination of extras the end-to-end Western Route can handle rather than picking only one route, turning some/most/all short-turns into thru trains, and spending capital $$$ sooner on the Medford track work that would entail. That's hardly an efficient way to achieve that goal. And I doubt they would ever want to
reduce the ratio of short-turns when they not only have a second routing to help augment Haverhill but those Haverhill rush hour trains can get pretty full by the time they roll inside 128.
More Reading turns, not fewer, are probably going to be needed to manage the demand.
Doing Reading station first matters because it lowers the pressure on getting in and getting the hell out of the way before the next train has to go there. They need that extra breathing room for all service. But it could immediately help bring some more short-turn slots...enough to track a bit better with recent growth. More meaningful spikes would have to wait until after the Wellington siding is done, and possibly after that prehistoric signal system between Melrose and Reading gets done over. But there's an indisputable priority pecking order on what capacity fixes they need to do...and DT'ing Ash St. through the Reading platforms is #1 above all else downstream.
The last public docs that showed a visual of the Wellington siding had it going from the current Medford Branch switch just past the Route 16 overpass and ending about 1 mile later at the Medford St. bridge (didn't say which side, although to use the 4th deck they'd have to backfill the first few feet of the abandoned freight siding incline on the other side to tie it back in). I think it was a Boston MPO document...either the Program for Mass Transportation or the regional needs assessment for the Long Range Transportation Plan. Google isn't turning it up right now.
