B&M days average about 150 minutes - Montrealer a little faster than the Vermonter - both trains used B&M NB only East Northfield to Brattleboro.
Montrealer/Washingtonian up through early 1980s about the same as B&M times.
B&M bad track days about 210 minutes on a good day. On a bad day it was quicker to walk.
The rerouted (1987-1995) Montrealer didn't hit Springfield , but WRJ - NHV was about 45 minutes longer than the schedule for the Springfield route.
Current Vermonter schedule allows 205 minutes, down from about 235 before the schedule change in 2013.
Of the current schedule 136 minutes are allowed Brattleboro - Springfield.
B&M allowed 14 minutes from Brattleboro to East Northfield, a little over 9 miles, with a track speed limit of 49. NECR allows 59, but there are a couple of curve restrictions. I find it hard to believe that the schedule would be much longer than 75 minutes from Brattleboro to Springfield even with the backup move into the station, making about an hour savings over the current arrangement. This is pretty much what we were promised even when the original proposal was made, which would have left part of the Conn River unsignalled with a 59 MPH speed limit.
Continuing on your nice piece of analysis...
Appendix B of the 2014 Operating Agreement between MassDOT, the MBTA and Pan Am it (linked on this board few weeks ago) says that the "Public Scheduled Amtrak Train Maximum Average Trip Time between CPR 1 and East Nortfield"(*) at the completion of the project should be
71 minutes.
(*) "Shown as an average scheduled running time of the southbound and northbound trains. The Public Scheduled Amtrak Train Maximum Average Trip Time assumes a preliminary Pure Running Time (''PRT") of 61 minutes, and 2 minutes of station dwell time at each of Greenfield and Northampton."
So the target scheduled time between Springfield and Brattelboro looks like it might be about 87 minutes, calculated as follows:
61 minutes (pure running time CPR 1 - East Northfield)
14 minutes (East Northfield - Bratlelboro))
6 minutes (station dwell time - 2 minutes per station x 3 stations)
6 minutes (move between SPG and CPR 1)
which would be a reduction of 49 minutes vs. the current schedule for the Vermonter.
Keep in mind that the "71 minutes" number is the target for the completion of the project in about 2 years.
