Anyone know why the platform is so large?

The widened station tunnel which previously contained both tracks and
the island platform (which was considered to be dangerously cramped)
would still exist, so now it presumably contains one track and one
platform in the same space, while a new tunnel containing the other
track and the other platform has been built adjacently to it.

Something similar was done at London Bridge, except that there were
two narrower station tunnels a few feet apart. One of them became the
passageway between the remaining one and a new one.

Angel station used to have lift access and a small island platform -
like Clapham Common. The station was very overcrowded as development in
the Islington area generated much more traffic.

It was rebuilt in the 1990s (?) with the new ticket hall and escalators.
The northbound track and platform stayed where it was and a brand new
tunnel was constructed for the southbound direction. The old southbound
platform and trackbed was filled in. The Southbound platform is
constructed to modern standards to cater for the demand at Angel.

A similar approach was used at London Bridge IIRC and the platforms here
are different sizes for the Northern Line. All done when the Jubilee
Line extension was built.

The date was 1992, but you've got southbound and northbound mixed up.
As the thread subject indicates, it's the southbound platform that
stayed where it was, and was widened to cover the space previously
occupied by the northbound track. The new tunnel and platform are for
the northbound.

I'd forgotten how very narrow it was!

Similarly at Euston, where there used to be an island platform on the
Bank branch. The arrangement was altered when the Victoria Line was
built, and the southbound platform (Northern Line, Bank branch) is wider
than normal as a result. Diagram of the changes at

So Angel and Euston used to have island platforms, and Clapham Common
and Clapham North still do: were there any other?

How embarrassing ;-) I knew my brain wasn't functioning properly and
this proves it.

That's certainly a good reminder. Getting down the staircase and onto
the platform was the "fun" bit.

What a fantastic photo... quite frankly, it looks terrifying to use.

For those unfamiliar with modern Angel, here's a photo of the widened
platform:

Are there similar worries about safety at Clapham Common or Clapham
North? I use them both with a fair frequency but haven't ever done so
during the height of the rush hour. I still find that walking down the
narrow island platform at either station a somewhat strange and
unfamiliar experience (I'd say they're both about the same width as
the Angel platform looks like in the photo). Presumably the station
staff at the Claphams are well on the ball about monitoring potential
overcrowding on the platforms.
