At least the second track through Beacon Park is funded, IIRC (correct me if I'm wrong). This is such a significant obstacle to running trains that perhaps the schedules will improve after it's done.The EGE wrote: New locomotives and coaches in the next year or so will make a big difference, as will getting Yawkey rebuilt with two platforms (and the second track reopened). So will removing the ridiculous speed restrictions near Worcester. But they really need the expensive fixes - raising those 7 low platforms, 2nd track through Beacon Park, and more space someday at South Station.
As for the low platforms, they must be made high platforms during any future alterations to the station (the new ADA rule from the FRA should apply now that these tracks are not owned by CSX); so they'll probably be relatively high priority.
