Paul of Waterways routes has found some more old photos of the station so I thought a second post was in order (incidentally the Chertsey blog's 1600th post).
This photo shows the entrance to the subway
You can see where the roof of the entrance 'porch' was. And it looks as if the original low wrought iron railing to the right is still there:
Kevin Smith has recently added four photos from 1987 to his Flickr account - starting here and then going back, two of the front and two of the arches (I'm guessing from the non-road side, accessed from behind the station).
But despite all our best efforts, still no photo of the whole of the front of the building from any time between 1901 and 1968!
While I'm here, here are a few more details from that walk.
Next to the bridge, temporarily fenced off because of what appears to be a small sinkhole in the pavement, is a rather nice information point in the form of a wheel. I only photographed the section pertaining to the station.
Just before I got to the station I found this ghost of a doorstep or entrance porch on the edge of a fenced off lot.
The local press have recently been reporting that Heeley Station and the line its on might re-open. I shall not be holding my breath.
