This is a lower-quadrant signal, as was standard on the GWR and the former Western Region of BR as it became - this means the arms move to point roughly 45 downwards to give a clear indication to the trains.
Though its basic principles are simple, the details get complex and technical, so are not most people's cup of tea.
If you do want to know more, these are the best places to start looking.
But as this site developed, from time to time I found I needed to include basic descriptions of some items appearing in photos and/or videos for which there was no readily available external site to link to.
After a number of these explanations had accumulated amongst my pages in wholly ad-hoc fashion, I eventually added a small dictionary of links to photos with captions that explain how particular items of equipment work.
But apart from those I'll leave the technical details to the experts, and concentrate here on sharing some highlights from my photo collection, as well as my reasons for finding a passion for signals!
Each has its own style of spectacle glass casing too, and see how the rightmost doll is missing its finial!
The distant (lower, yellow) arms on the second and fourth dolls are of an unusual pattern that was only found at Newton Abbot - these are operated by motors (the black boxes) mounted immediately behind the arms themselves, a very rare arrangment, and again have a distinctive spectacle glass holder design. The shorter home arm on the very left leads to a lower-grade goods line, and the distant arm on the 3rd doll is fixed to indicate that trains must always proceed with caution when travelling by that route.But if you look more closely you will start to see the unique variations that can sometimes be found even on one signal gantry.The home (top, red) arms on the two middle dolls are a standard Great Western design made from wood, while the one on the right is a later BR pattern in metal.The last surviving semaphore signals on Greater London passenger lines.Includes a short video clip of the signals in action when Chiltern and WS&MR trains were diverted to Paddington, and photos of the box from an official visit in July 2010.It has four 'dolls' because there were four possible lines a passing train could be routed onto.
