The Surrey Iron Railway

Does anyone organise walks of the line?

I don't know (although the tiny Wandle Industrial Museum might).
However, I do recall that the standard short book on the SIR (*)
includes descriptions and maps of a number of walks you could take along
the line.

(*) I seem to have mislaid my copy, but I'm pretty sure it must be
"First public railway - Surrey Iron Railway" by Derek Bayliss. Available
from the Wandle Museum:
