What is/was this?

On the crossing at the bottom of DKH. I'm thinking something to do with the trams, it has an electric switch on it. Thanks!

If no one knows the answer, perhaps you could send it in to Robert Elms's Radio London show on Wed for the notes and queries bit?

Never noticed it before in twenty years! Intriguing...it could be to do with the trams but I think the central reservations were only put in after the trams stopped running, so it would be odd to leave it there.

No dual carriage-way refuge until at least 1954 when the tram tracks were removed.
