There's a pub on Kennington Park Road called The Old Red Lion. A
little to the north of Kennington tube station. Not far, just a train
length or so.

I drove past it the other day, and next door - a yard - had a large
hoarding round it. Marked "london underground", or similar.

Now kennington tube station is having some work done to it.

But there's no evidence of a link to these hoardings from platform
level. It could be connected to the old passages - before they rebuilt
kennington for the other northern line branch - hidden away one floor
under the lifts, and on the train side of one of the platforms.

Except, the thing is, the platforms at kennington are to the south of
the station, and the station is more or less at the northern end of
them.

So what is the hoarding for?
