Torch indicating point's position

The railway signals give instructions to drivers, indicating whether to stop or continue and in what running conditions should they follow.
From the beginning, the railway signalling systems have sought to guarantee the necessary safety conditions for the circulation of trains along the railway network. Originally these were mechanical, very simple and safe, operated by on-site levers.
The Road Change Apparatus is a mechanical installation made up of different components, from spears, needles and other mechanical parts which allows railway trains to be guided from one track to another.
The torch indicating point's position is a four-sided lantern with opal glass or a reflective bent iron plate. This signals the operational route, indicating the position of the needle and the established route.
