Embarcadero and Montgomery stations are on track for a $900 million expansion, complete with new tunnels, elevators and extra platforms to boost rider capacity. That's great news considering almost daily, around 5:15pm, the platforms are so crowded that the passenger lines have to wind around in circles, causing a back-up at the bottom of the escalator as people pour into the station. I've seen people trip and fall due to the back-up since they have no where to step when the escalators come to an end.
What do you think about this upgrade?
