Example Sentences
- "Colour-light signals, for both day and night work, came into use at a much later date, and their first use on any scale in this country was on the London underground railways, where the principle adopted was largely American in origin. But although light signalling is credited to America, one of the first instances of its use was an experimental installation at Herne Hill, although it did not find favour in this country for overground working until some fifty years later."
