My guess is the idea is to close everything down on Tuesday in the hopes that most things can be up and running again on Wednesday. Certainly that seems to be the plan at Logan.

I also think that the infrastructure of the MBTA is not as robust as it was in '78, but I could be wrong. Also my vague recollection of '78 was that there were days and days of no travel, and I'm sure everyone wants to avoid that this blizzard.
