to get to a train with only a few minutes' warning.

I think one reason for the latter is that the current low-level bay
platforms are quite narrow, so they don't want departing pax filling them
too soon. It can be a real scrum when a packed 12-car train arrives, and
there are departing pax waiting on the platform.

I can't say I took a tape measure with me but I didn't the platforms were
especially narrow apart from around the steps up to the bridge. At the
mainline terminuses I'm most used to at peak hours, Waterloo and Liverpool
Street, you often get people waiting on the platform itself and you can get
a turnaround. And London Bridge evening arrivals are not noticeably packed.

"Platforms 10 and 15 are narrowed to allow work to continue behind the
hoardings. It might take you longer to get off your train and pass through
the gates during the morning rush hour/morning peak."
