I seem to remember reading the answer to that question here
already. It's because HMRI won't let any new railway start up
using unprotected conductor rails like those on the tube.
Presumably they consider the EOR to be a new railway.

So, how does one "protect" them, then? Are we talking those wooden
planks either side of them?

An example of protected conductor rails is the Docklands Light Railway.
It looks like a sort of curtain rail and the current shoe runs
underneath it. I'm not quite sure of the exact mechanics.
