In terms of running railways, signals are mechanical and electrical devices erected beside a railway to pass information relating to the state of the line ahead of the engine.
Signalmen use these to direct an engine's crew to make certain movements or to stop from their signal boxes. However, sometimes either the signalmen or the engines do not pay attention, often resulting in accidents
The signals on Sodor are old-fashioned, semaphore railway signals, still used in some countries today, mostly in the United Kingdom. They are also found on vintage railways and railway museums that preserve both steam and diesel locomotives as historical pieces, such as the Illinois Railway Museum in the United States. The majority of signals seen in the show are lower-quadrant semaphore signals, which means the arm of the signal goes down to show green.
These particular signals are based on the signal gantry that was used between S1-4.
