I got an email from the RTA on Thursday to say that this staircase had been cleaned by their contractor.
The contractor had indeed cleaned the underpass nearby, but had completely missed this staircase, which is what I specifically asked them to do.
It may turn out that the staircase is Council property, but if that is the case, has the RTA bothered to tell Council that this needs cleaning? I have sent these photos back to the RTA and told them that their contractor has missed a spot.
The "art" on this staircase includes "f*#k fagot metro c*nts". Lovely.
