Opening TRANSYT 15.5 files in 15.1 and 15.0

Due to the significant enhancements associated with using multiple analysis and demand sets, the TRANSYT 15.5 file format is substantially different to that of TRANSYT 15.1.1 and other earlier releases of TRANSYT 15. Therefore, files imported into TRANSYT 15.5 and re-saved cannot subsequently be opened in earlier versions of TRANSYT.

If you have a client or colleague that needs to view the contents of a TRANSYT 15.5 file and has not yet upgraded, they can download the demo version for TRANSYT 15.5 and view and (evaluate) run the files using that version straight-away. Please note that unlike previous “Demo and Viewer” versions of TRANSYT, you can now carry out evaluation runs (i.e. using existing timings) of all analysis sets within the file using TRANSYT 15.5. This change ensures you will have full access to all the results and all associated network diagram animations.
