That was quite interesting, looking at the stations with fresh eyes. I hadn't actually clocked why there are no ads on the opposite walls for example.
Living here so long you forget / don't realise there is a lack of signage to the overground rail station - do newcomers really not realise it is there?
Also blue sign at rear of tube station, presume that is left over from when it was a way into the the station along the parade of shops but maybe presenter didn't know that, as it was a while ago that it closed when tube was renovated. How long ago was that?
