The brambles are back, but sensibly equipped with secateurs. Only thing to add to previous logs is the the wall is about 5m north from the Thames path along a distinct path through the vegetation.

Somewhat obscured by brambles. The fb faces the river on the wall at right angles to the face of the bridge.

This is extremely overgrown again. The only way to approach it is from the W side of the bridge via the low arch N of the Thames path. It's just beyond the E end of the 'tunnel' on the wall on the left. I bushwhacked some of the brambles to get a clearer view. http://maps.jochta.com/benchmarks.php?id=483

Last time I was here, the mistake I made was to look on the bridge. It's not on the bridge itself. dal has made an excellent job of clearing away the brambles; the FB is clear and easy to spot from the footpath.

Success. I went prepared with secateurs and trowel. I didn't need the latter. As I cleared the brambles, the FB emerged reasonably high on the wall. N side of river, N side of footpath, E side of railway, S facing on the retaining wall to the east of the bridge, just under 2 m from the bridge. The carved BM 49 FT on the buttress dividng the footpath is a red herring.

Agree with dal. There's no shortage of spoil piled up around the bridge, under which the FB may well be hiding. Description doesn't say which side of the bridge the FB should be on, but the GR seems to imply the east side. This is also the side with the 'BM 49 FT' inscription seen by dal.

Couldn't find it. Railway bridge well used. BM 49 FT carved in stone, with a chalk arrow pointing underground. There has been significant work on the river bank (which carries the Thames Path) in the last few decades. Possibly buried? Note at 165.352ft it is higher than the neighbouring BMs at Clifton (159.020ft) and Culham (162.920ft)
