Took a walk down to the crossing late last night, as I was up and wanted to see if there would be a crossing guard present at High St late at night. Though it normally departs North Station at 10:30 p.m., Amtrak 688 was scheduled to leave North Station at 11:25 p.m., which is the normal time for nights when the Red Sox/etc. have home games. As such, I figured it would be interesting to see if the guard would be present for not just a late-night train, but a later-than-usual train.
Sure enough, the guard's car was parked there when I got to the crossing around 11:30. When the (electronic) bells started clanging, he came running out of the woods by the track. I don't know if he was using "the facilities" or having a smoke break, but I found it pretty humorous. He did his schtick, and I figured he would be going home. Turns out he stayed for the last two (one inbound, one outbound) Lowell line trains, the latter of which came through around 12:25 a.m. Obviously he was just doing his job, and I very much get having that crossing staffed during peak hours, and I agree that the intersection is a mess, but I did find it a bit unnecessary to have a guard there during (very much) off peak hours when there was virtually no automobile traffic.
