The PAS grant was for stabilizing the current Class 2 speeds. Pan Am, despite its post-2008 reinvestment in the Patriot Corridor, still left lots of deferred maintenance to patch. PAS has had to play whack-a-mole with constantly popping-up 10 MPH speed restrictions for years. An uprate to full Class 3 would probably cost close to $100M given the number of track miles that are teetering at barely Class 2. And Berkshire & Eastern really doesn't need need greater than 25 MPH speeds to run a network hubbed centrally at East Deerfield Yard. The more time-sensitive Norfolk Southern intermodal is moving to B&A trackage rights as soon as the Worcester Main's double-stack clearance improvements are completed later this year. Autoracks, trash, and general freight staying on the Patriot Corridor really don't have the same time sensitivity.
Not on the Alternative 1 (lower-investment with Class 3 track) and Alternative 2 (higher investment with Class 4 track) options that got the most attention. It was North Station--Porter Square--Fitchburg--Greenfield--North Adams on both those Alts. Alt. 3 electrified service added 1 more intermediate in Athol. Alt. 4 "local service" took Alt. 2's Class 4 track and added stations at Gardner, Athol, and Shelburne Falls. Alt. 5 took Alt. 2's Class 4 track and did NS--Porter--Fitchburg--Greenfield--North Adams--Schenectady--Albany. And Alt. 6 did a Fitchburg-North Adams shuttle with stops at Fitchburg--Athol--Greenfield--North Adams and forced transfer to Commuter Rail.
All of them fail for not including a near-128 (Waltham Center or Weston/128) and a near-495 (Littleton) intermediate to tap demand on the existing Fitchburg corridor. As per my earlier post, Fitchburg is only 6th on the commuter rail line in boardings after South Acton, Waltham Center, Concord, West Concord, and Littleton. And the 5 Alts. that omit Gardner all end up omitting the highest-population ridership node on the new-service corridor. As a ridership generator this study is defective by design for all that it omits.
