IntroductionSignaling system world over are provided not only to make optimum use of the existing line capacity, but also to provide safe train operation by reducing human dependence Rail signaling and safety systems provide smooth operation of suburban and mainline railways. They are complex facilities consisting of various subsystems and devices, which must be properly matched. Each component, from interlocking to point machine, is basic to safe railway operations especially in view of the increasing demands to be met by modern railway systems. Interlocking is a mechanism to check the route the train is going to traverse before clearing the signal and to prevent the clearing of signal when it is unsafe for the movement. Automatic train control systems from Siemens are an essential component of rail signaling and safety. It eliminates human error and ensures safety in train operations. It also controls points, to allow train to change the line. Track circuits, which used to detect train presences are also controlled by interlocking system. SCADA systems are typically used to perform data collection and control at the supervisory level. Some systems are called SCADA despite only performing data acquisition and not control. SCADA is the acronym for Supervisory Control And Data Acquisition. The supervisory control system is a system that is placed on top of a real-time control system to control a process that is external to the SCADA system (i.e. a computer, by itself, is not a SCADA system even though it controls its own power consumption and cooling). This implies that the system is not critical to control the process in real time, as there is a separate or integrated real-time automated control system that can respond quickly enough to compensate for process changes within

the time constants of the process. The process can be industrial, infrastructure or facility based.

HISTORY

Siemens was founded by Werner von Siemens on October 1, 1847, based on the telegraph he had invented that used a needle to point to the sequence of letters, instead of using Morse code. The company then called Telegraphen-Bauanstalt von Siemens & Halske opened its first workshop on October 12. In 1848, the company built the first long-distance telegraph line in Europe; 500 km from Berlin to Frankfurt am Main. In 1850 the founder's younger brother, Sir William Siemens (born Carl Wilhelm Siemens), started to represent the company in London. In the 1850s, the company was involved in building long distance telegraph networks in Russia. In 1855, a company branch headed by another brother, Carl von Siemens, opened in St Petersburg. In the 1950s and from their new base in Bavaria, S&H started to manufacture computers, semiconductor devices, laundry machines, and pacemakers. Siemens AG was incorporated in 1966. The company's first digital telephone exchange was produced in 1980. In 1988 Siemens and GEC acquired the UK defense and technology company Plessey. Plessey's holdings were split, and Siemens took over the avionics, radar and traffic control businesses
