Симулятор железнодорожной сигнализации SimSig: Реализм и обучение

SimSig is a mixed donationware and commercial Windows based train simulator of modern railway signalling systems in Great Britain, from the point of view of a railway signaller. Users have also had success running SimSig on Linux using Wine. The program was written in Delphi 6, a dialect of Object Pascal, by Geoff Mayo and has been in development since the late 1990s. Visually, it resembles the British Rail Integrated Electronic Control Centre (IECC), though most of the simulations do not cover areas operated by IECC based signal boxes. It simulates overlaps, approach locking, time of operation point locking, shunt routes, warner routes, call on routes, and more. Railtrack asked for a "professional" version of SimSig, now known as TREsim, which is currently used to train signallers at every Network Rail IECC and several panel signal boxes around Great Britain.

Train motion is simulated according to train type and loading, and is controlled via the use of timetables. With a keyboard and mouse, the player sets routes and operates level crossings as necessary as well as simulations/timetable specific tasks such as operating ground frames. Solid State Interlockings (SSIs), the main electronic technology in use at present on British railways, along with approach locking, swinging overlaps, shunt routes, warner routes and call on routes are all available. are functional in some of the available simulations. Most simulations have various levels of difficulty, ranging from beginner to difficult scenarios with engineering possessions of tracks; train delays; bad weather; or points, signal and track circuit failures. Although produced by railway software engineers to ensure a high degree of realism, the simulations are usable by those without any in depth or professional knowledge of signalling systems. Most simulations can be joined over the Internet to share the workload. Some simulations can be linked to form a chain of signal boxes for extended operation. A total of 40 simulations are currently available covering England, Wales and Scotland. Beta versions are no longer publicly available. Many of the older simulations are based on the real life IECC screen layout with multiple pages or panels to display different parts of the simulation whereas the newer simulations have one scrollable panel which covers the entire simulation. As of July 2013, a new method of installing, running and updating compatible simulations, the SimSig Loader, was introduced. The SimSig loader allows for the opening and updating of most recent simulations via a single program as opposed to the individual exe files of previous simulations. In September 2018, support for using operating systems prior to Windows 7 to find updates was discontinued. This includes both the loader and licence manager.

User created timetables simulating modern, historical, and fictional scenarios are available through simulation forums and other web sites. Timetables may be created with the built in editor
