Engineering study is fully funded and ongoing, with construction funding sources mobilizing at the state level. PAS is definitely front-loading that as a maximum priority. It is probably the most important thing in the world from the NS half of the partnership after finishing up the 286K mainline upgrades scheduled to wrap by year's end. And now that the CSX double-stack job has wrapped this is the next-highest priority in the Mass. State Freight & Rail plan. Once the engineering is done we'll probably see this one start to mobilize fast.
When completed will this reduce or increase congestion on PAR/Patriot Corridor?
It reduces congestion on CSX, but they have had 315K weight since the Conrail era, Class 3 speeds since before the Conrail era, a lot more intermodal business to begin with, and fewer online customers on the west-of-Westborough main necessitating fewer locals. So the reduction in trains that came with stacking was a lot more dramatic for them, and with their intermodal growth being evolutionary (but healthy!) it'll take a longer time to refill that cup. And also lopping off Beacon Park and doing some trimming in MBTA territory has consolidated a ton of locals that used to be whizzing all around Eastern MA. PAS isn't comparable because they were stuck at 263K for the longest time, stuck at even
lower Hoosac clearances that couldn't take a full-size autorack for the longest time, have more online customers to serve, more branchlines with online customers to serve, and are starting near the beginning of the growth curve for serious intermodal revenue. For them it's likely going to mean traffic spikes up.
At least, that's what NS is banking on. They wouldn't have touched Ayer with a 10-mile pole if a majority of the benefit was just ops efficiency. More ops efficiency on very mediocre business still means you've got a big problem to solve of mediocre business. They want big business. And soon.
