Finally found the elusive location for the railway crossing/gasworks/ Chase Scenes, it is Bushy Park Road, Edenton. Originaly did a bit of Sherlock deduction, tried following all the Southern Region Railway routes out of London using aerial shots from Google maps, but to no avail as most of the gasworks I was looking for had been demolished with the advent of natural gas, and then I remembered an old AZ of London, given to me by an old employer, when I started driving for a living in the early 60's, although well out of date then it did help me get around, but I specialy remembered the ancillary info on the maps, and that was factories, gas works, piers, wharves, and places of interest all drawn and named, so it was off to Ebay and searched for "Bartholomewís atlas of London circa 1920's, lo and behold a few were there, got a copy for a fiver, and when received, searched thoroughly, and bingo!, found it, in Teddington, Middx.
The gasworks have completely gone now, as has the level crossing, but there are three positive shots that redeem it as a find, these are, a scene where Nanette Newman in the white sports car, and Peter Sellers sports car, drive along Bushy Park Road, panning shot of terraced houses, that are still there, the shot off John Le Mesurier standing by the ice-cream van as the sports car does a 380 turn, in the distance is a wall that surrounds Bushy Park (Hampton Court Park not Watford, which is spelt Bushey with an e), which is on the road from Teddington to Kingston, this wall is also seen in the distance in the shot of Bernard Cribbins on the out building roof next to the crossing opposite the Signal Box, again of which hardly anything is left, back to the John Le Mesurier shot, also in the shot of the far wall is a pedestrian gate into the park, just discernable on the shot, which leads to the third confirm, which is the shot of the police car waiting to chase the Peter Sellers car, a quick change scene integrated with the Uxbridge scenes, which is the far left hand corner of the Le Mesurier scene street, as panning round from this scene is a shot of the pedestrian gate mentioned. Also worth a mention is the scene where a villain is running up the railway lines, with a gasometer in the distance, it was in fact taken form the level crossing, as the gasworks straddled Bushy Park Road, and all the ground seen from the scene with Bernard Cribbins on the out building, was in actual fact the old gasworks ground, demolished and cleared in favour of natural gas that was coming in the future.
My own shots, although a lot has changed and missing, still captures some of the old scenes, albeit some, because of access difficulties have had to be taken from other angles, Plus what's left of the Bernard Cribbins scene building, I will send as usual in small doses with captions as well as map views, again then and now, with and without level crossing.
Hope you enjoy these shots, some of them just go to prove when itís gone,it's gone, a good reason for folks to get out with their cameras now before it is gone forever!
There is one other scene I am chasing is where the crooked police put up the road diversion sign for Notting hill, in what looks like Buckinghamshire!!, if you get a chance to review look out for the coach?, seems to be in every scene, and each scene is in about a 100 yard area, with some scenes taken to the left when all the chase is to the right, meaning they have gone back on themselves to shoot, you could write a book on this film.
