Early manual signalling methods were gradually refined and replaced on UK railways so that by the 1890s the systems familiar into the mid-20th century were standardized across the network. This concise history traces the evolution of signalling from the 1830s to the end of the steam era and is illustrated with photographs and diagrams explaining technical developments.
