The program was written in [Delphi 6](/source/Delphi_(programming_language)), a dialect of [Object Pascal](/source/Object_Pascal), by Geoff Mayo and has been in development since the late 1990s. Visually, it resembles the [British Rail](/source/British_Rail) [Integrated Electronic Control Centre](/source/Integrated_Electronic_Control_Centre) (IECC), though most of the simulations do not cover areas operated by IECC-based [signal box](/source/signal_box)es. It simulates overlaps, approach locking, time-of-operation point locking, shunt routes, warner routes,<ref>{{cite web|url=http://www.rgsonline.co.uk/Railway_Group_Standards/Control%20Command%20and%20Signalling/Codes%20of%20Practice/GKRC0721%20Iss%201.pdf|title=Code of Practice GK/RC 0721; Section 1.4.2.3 Main or Warner Class Route Selection|publisher=Railway Group Standards|accessdate=2015-07-01}}{{dead link|date=September 2017 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> call-on routes, and more.

A total of 40 simulations are currently available covering England, Wales and Scotland.<ref>{{cite web |url=http://www.simsig.co.uk/dokuwiki/doku.php?id=usertrack:mans:manuals |title=Simulations Manuals  |publisher=SimSig |accessdate=2014-01-27 }}</ref> 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](/source/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 content ===
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<ref name=rf2004/> or an imported text file. Sources for timetabling information include official Working Timetables (WTT) and historic published timetables such as [Bradshaws](/source/George_Bradshaw).

A timetable file converter allowing easy conversion between timetables and text files is available from a third-party site.<ref>{{cite web|url=http://www.davros.org/rail/simsig/|title=SimSig|publisher=Clive Feather|accessdate=2008-12-26}}</ref>
