Dear Keith, Your letter was passed onto me and I can definitely confirm that it is COMMON LANE CROSSING, the first crossing south of Templecombe. It is taken looking south , the house unfortunately did not survive as during rebuilding the walls became unstable due to there being no foundations!!! However a replica house was constructed, but double the size with two gables and a replica porch in the same location as the old. The GLR now crosses the road at the old location on our new northern extension , I attach a photo of the same location today. The other location you were thinking of PARK LANE CROSSING on our southern route still has the gate posts, one kissing gate but unfortunately the house is long gone. Also in the picture above is the sleeper built PW hut, it was only two years ago when we installed a new gate that we finally removed the last of the sleepers that formed the rear wall of the hut.
Regards C.J.Penny GLR Many thanks to John for this information and for both of the photographs below.
