Apparently neither the J or the N could enter to the underground behind Safeway, AND all the underground trains couldn't move because of an all station stop due to computer malfunction.
Here is my view from the inbound platform.
The entire inbound side of the station (even the areas where the train doesn't stop) were packed with people.
All the officers and Muni-esque officers were told to just send everyone to Church St. Station so that there weren't a hundred people wandering the streets looking for cabs. But when they got there they quickly found out that the underground wasn't moving either. Church Station turned into a disgruntled holding tank. The above photo is a view from the street of the stream of people all headed towards the ALREADY packed Church Station.
Wow. What a nightmare.
Now back to you Diane.
