I think I know how this happened.

Someone legal at Cityrail sent a memo to the Client Safety Office, stating that warning signs should be painted on platforms across the entire Sydney rail network. Perhaps the memo read something like this:

These warning signs should be clear, concise, and leave no margin for ambiguity. We suggest they read "SURFACE MAY BE SLIPPERY WHEN WET".

This memo was cut and pasted into a contract requisition to Signs-R-Us, who sent an order to their stencil-makers, who made dozens of stencils. These were then sent out to station-masters across the network, who dutifully flopped the stencils on the ground, got out their supplied cans of yellow paint, and sprayed the signs, complete with the unnecessary quotation marks. Thus:
I catch a lot of trains. This is going to be a disproportionately huge annoyance for me. Srsly.
