Does this photo look like remains of the Crystal Palace Pneumatic Railway to you? If so then please can you explain how the 2 wooden objects, including the metal thing in-between, fit into a railway system! Also, don't forget to mention which direction you think the railway track was running. Kenny should be good at this one I reckon... hopefully, he'll tell us it's something else other than a railway!
The excavation was carried out in the late 80s, and the above view is looking directly down into the bottom of the trench; they were only allowed to dig one trench, which brings me onto my next question: could they have really known exactly where to dig based on an aerial photo!?
Obviously, the ground looks very rough in places, particularly where the funfair used to be sited inside a tennis court, but still... I don't believe they could find the Crystal Palace Pneumatic Railway from an aerial photo. Looking at the colour view above (they used an inferior B&W one), can you trace lines where you think sections of the railway line may have stretched? Also, If you manage to spot any Roman trackways or Saxon field boundaries then do let us know!!!
