Back when the CNJ still ran to Jersey City, when weather conditions in New York Harbor required the ferry operation to be suspended, CNJ conductors on the Raritan trains issued a Fog Ticket to each New York passenger, good for passage on the PRR from Elizabeth to New York. The New York passengers would all bail out at Elizabeth and go upstairs to the PRR station to board PRR trains to Newark and Penn Station (I assume the PRR must have put on passenger extras -- there's no way scheduled trains could have handled that number of additional passengers). The PRR conductors (assuming they could get through the train) would lift the Fog Tickets and turn them in to the PRR ticket receiver to be sent to the CNJ for reimbursement. If the Weehawken ferries were socked in, did the NYC have a specific emergency plan for dealing with passengers pouring off the trains in Weehawken, no similar transfer arrangement with another railroad being possible? Erie and DL&W passengers could just use the H&M, but there was no good way for large numbers of passengers to get from either the CNJ or the West Shore to Manhattan. Was there anything the NYC could do in those circumstances?
Interesting question-- I don't know the answer.
The CNJ ferries would have had to cross the river in a fairly busy part of New York Harbor, I think-- the New York Central's Weehawken ferries, if they were where I think I remember there were ferries in the early 1950s, would have been a bit further upriver, in an area with less intensive water traffic: I suppose it is possible that at that location it was deemed safe to cross-- maybe a bit slower than usual, and blowing the fog horn continuously-- in conditions worse than the CNJ ferries would dare.
But that is total, groundless, speculation on my part.

Umm. I'm assuming that the Weehawken ferries were the ones whose New York terminal was at about 125th Street?
