2009/06/16, 1. The starting signals at the south end of platform 7 at Shrewsbury are delightful GWR lower quadrants with short arms combined with spectacle plates - each arm is different! These are Severn Bridge Junction signalbox's signals No. 11, the box itself beyond the signals. The left hand arm is for departures towards Wolverhampton while the right hand arm is for the Hereford line. Tuesday 16th June 2009. The photos are a "Stereo Pair", and thus when looked at correctly, form a 3D image. In order to view this image, sit well back from your screen, look at the join between the two photos and then attempt to go "cross eyed", focusing your eyes just beyond the end of your nose as it were. It takes some practice, but eventually the two images will merge in the middle and produce the 3D image in the centre (you will still see images to the left and right of the 3D image). Once you have got it, your eyes will "lock-on" and you can look around inside the image. Enjoy, but don't strain your eyes! Unfortunately, the technique used for producing this image cannot be used for moving trains! There is a "normal" version of this shot in the "BR Western Region" collection.
