All the T personnel we interacted with were extremely professional and impressively competent. Along the tunnel,they had a sort of bucket-brigade of people along the route warning us of every tripping hazard or wet spot and shining flashlights for us. They clearly know how to handle stuff like this, and I think if there’s ever a zombie apocalypse, I hope plumtreeblossom and I end up with a bunch of MBTA employees.
The passengers, with one slightly grumpy exception in our car, were quite understanding and pleasant during our shared ordeal.
We were so drenched by the time we got out. The A/C was on on our train until they decided to evacuate (and turned off the third rail), and it wasn’t too bad after that, but the tunnel was pretty hot and muggy. [EDIT: I suspect they never actually turned off the A/C, just turned it down to conserve power. Not sure. It was pretty warm walking in the tunnel, though.]
I haven’t looked at it yet, but plumtreeblossom says we made it onto the TV news, at about 3/4 of the way through this video.
PS — Meant to post this yesterday, but with catching up at work, dress rehearsal, and the limitations of my phone keyboard I never managed.
