On a rail transport system, signalling control is the process by which control is exercised over train movements by way of railway signals and block systems to ensure that trains operate safely, over the correct route and to the proper timetable. Signalling control was originally exercised via a decentralised network of control points that were known by a variety of names including signal box (International and British) and interlocking tower (North America). London Underground call them signalling cabins, and the Great Central Railway referred to them as signal cabins. Currently these decentralised systems are being consolidated into wide scale signalling centres or dispatch offices. Whatever the form, signalling control provides an interface between the human signal operator and the lineside signalling equipment. The technical apparatus used to control switches (points), signals and block systems is called interlocking.

Signalling control in the context of Hard infrastructure
Hard infrastructure, also known as tangible or built infrastructure, is the physical infrastructure of roads, bridges, tunnels, railways, airports, ports, and harbors, among others, as opposed to the soft infrastructure or "intangible infrastructure of human capital in the form of education, research, health and social services and "institutional infrastructure" in the form of legal, economic and social systems.
This article delineates both the capital goods, or fixed assets, and the control systems, software required to operate, manage and monitor the systems, as well as any accessory buildings - such as airports, plants, or vehicles that are an essential part of the system. Also included are fleets of vehicles operating according to schedules such as public transit buses and garbage collection, as well as basic energy or communications facilities that are not usually part of a physical network, such as oil refineries, radio, and television broadcasting facilities.

A junction, when discussed in the context of transport, is a location where traffic can change between different routes, directions, or sometimes modes, of travel.

A junction, in the context of rail transport, is a place at which two or more rail routes converge or diverge. The physical connection between the tracks of the two routes (assuming they are of the same gauge) is provided by turnouts (US: switches) and signalling.
