An experiment in polite complaining! This is part of a test ride I did this afternoon, which I plan on posting about later but...
Coming back from the city centre shambles (at around 16:50), I reached the dropped kerb at Haymarket Yards leading to the Roseburn Path, only to find tram construction vehicles parked on the kerb and with their compressor completely blocking access to the shared path on the dropped kerb. A workman called to me from the residents' car park, where he'd just got out of his van, to reassure me the path was open(nice man, thank you). He even told me where it led but I replied that I knew.
Anyway, there were about a dozen men concentrated on the tracks and the compressor was in use. I stopped and calmly pointed out that the compressor was blocking the only dropped kerb access to the cycle path and asked if they could move it even a metre or so to one side to permit access. One of them assured me it would be moved. He sounded genuine enough about it and maybe they really didn't know they were blocking a cycle path, or at least that they were making access difficult.
Anyway, if anyone's heading that way today (or tomorrow even), it would be interesting to know that - if the compressor is still there - that it has been moved to one side.
