Just noticed this morning a new section of rail which looked like it
might not be made of standard railway line steel.
Are they steel or something else which conduct better, since they
don't have to take any weight?

There's a relatively new design of conductor rail by Brecknell-Willis.
It consists of an aluminium extrusion (for lower resistance to
electric current than steel) bonded to a stainless steel wearing
surface.

Is that perhaps what you saw?

Sounds like it, thanks
