SwitchWithIt Ver 1.7.10.26 is available for download at SourceForge.Net: https://sourceforge.net/projects/switchwithit/ This new version changes the way that cars are selected for a train so that there is a more even distribution in the selections. See the Readme file for more detail. Also, Windows 10 and 11 continue to try and restrict programs that are not on the Windows Store. Windows 11 now requires that the program be run as Administrator. New instructions have been added to the Miscellaneous Tab in the program. David
