British Railway Signalling
Railway signalling has always fascinated me, and I love to see model railways with a good representation of signalling. I appreciate the fact that it’s not always possible to add realistic signalling to all of our railways, and the fact that signalling may appear to be a mix of magic and confusion to some. When all is said and done, signalling just provides a safe method of moving trains.
This documentary goes into some depth about the functions of railway signalling, but will hopefully shed some “signal” light onto the subject for anyone confused by the black art of Railway Signalling.
