Thanks for those great pictures - is it just me or the crossover hasn't been put into the catenary yet?  Looks that way.  Anyway, fantastic to see it taking shape, looks like a proper urban railway now.

With regards to those signs, "Danger live overhead wires" is probably going to temp some ferals who otherwise (without the signs) probably wouldn't even be aware of them.  Oh well... as my old grandpa used to say, you'll never stop stupid people doing silly things.
