I rode the first inbound train from Concord, MA, this morning (Friday, August 4). It was on time or nearly so. Between Waverley and Belmont, I think, one of the crew made an announcement over the PA system: the drawbridge to North Station was stuck in the up position, and the train wouldn't be going beyond Porter Square for a long time. The dispatcher said everyone should get off and use the Red Line subway from there to get into Boston. I was getting off at Porter anyway and didn't stay at the station to observe further developments.
It would be interested to know how this is handled. The first train could be sent farther on to clear space for other inbound trains to unload. Probably three or more trains could fit between Porter and the drawbridge. BUT, outbound ridership during rush hour, though not nearly as heavy as inbound, isn't insignificant. Fortunately, private schools in Weston and Concord to which many students commute from Porter probably aren't in session.
P.S. The "time stamps" on messages on this forum must still be in Eastern Standard Time. I posted the above just a minute or two ago, and it's now 6:55 a.m., EDT.
