Closed-circuit televisionClosed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring (Videotelephony is seldom called "CCTV").
Conservation and restoration of rail vehiclesConservation and restoration of rail vehicles aims to preserve historic rail vehicles. It may concern trains that have been removed from service and later restored to their past condition, or have never been removed from service, like UP 844, the only U.S. steam locomotive to never be retired. They are often operated in present-day service as moving examples of living history, as opposed to static exhibits.

Communications-based train controlCommunications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This makes railway traffic management safer and more efficient. Metros (and other railway systems) are able to reduce headways while maintaining or even improving safety.
