This version of TRANSYT was first introduced in 2003.  This version introduced the first graphical representation of the network and allowed many network features to be constructed graphically using the Network Construction Editor (NetCon).

Please note that although support for this version of TRANSYT is still offered by TRL, use of it on operating systems which were released after the main development of this version cannot be guaranteed, i.e. Windows XP (Service Pack 3 onwards), Windows Vista, Windows 7 and all 64-bit systems cannot be guaranteed.  Any lack of functionality caused by using TRANSYT 12 on these platforms cannot be repaired.  For example, it is  known that CYOP is most likely to fail when running files that contain flares with TRANSYT 12 on Windows 7.  If you experience problems with the product on these platforms we strongly recommend upgrading to our latest product, TRANSYT 15.

The current maintenance version of TRANSYT 12 is version 12.1 (Release AH/8).

Further details about the TRANSYT product can be found on the main TRANSYT page.
