Very interesting. I used to watch a lot of those trains at the gate tender's shanty on W. Wyoming Ave. in Melrose, MA. Some observations:
Boston-Lawrence back then was done in 27 minutes, no stops.
The only division that had food and parlor service was the Portland Division, from what I could tell.
There was a listing of a milk car from Enfield, NH to Lawrence. I wonder how that got from the New Hampshire Division over to Lawrence. The M&L?
I thought the Gull had a sleeper destined to Halifax, NS. This document shows it terminating in St. John, NB.
I didn't read the whole document. Was the Talgo Train in there?
