The rails were visible at the Norwood depot for a while a few years
ago, until the entrance was resurfaced.

During construction of Croydon Tramlink various short lengths of old
street rail were dug up, but these didn't seem to be where trams had
previously run, and some were running across the street, so I assume
they were old scrap rails which had been used for some other purpose;
to strengthen the road where it passed over something like a sewer
maybe?

The rails, and conduit, are still in place on the ramp of the old
Kingsway subway of course.

I suspect that there's still quite a bit of old rail covered up in
various places. Does anyone know of any more.
