From the head on shot it looks quite well displaced laterally
When "they" passed through our village, South Stoke, the airborne part of the duet was about 50 feet above the train, most certainly not offset. Appalling.
The hill the other video was taken from is clearly visible too.
I beg to disagree, The first video with the duet crossing Gatehampton Bridge was taken from the high ground to the East of the line. The second video from the "Leathern Bottle" bridge (between Goring and South Stoke) is looking South so the hills to the right of the shot are above Streatley on the Western side of the railway. The location that the first video was taken from, about two miles distant, is behind the trees on the left of the shot.
