Many of the templates will self install, and all the user has to do is to point the installer at the train simulator directory. Almost all templates are set up this way, except for some older templates, which we will eventually upgrade to AG4.
For those which do not self install, you would need to upzip the template to a temporary folder. At that point there are two possibilities.
First, if the template unzips into the basic folders (ACTIVITIES, PATHS, SERVICES, TRAFFIC, and CONSISTS), then all you have to do is to copy the CONSISTS folder into the TRAINSET folder in the main train simulator folder. Next copy the four remaining folders (ACTIVITIES, PATHS, SERVICES, TRAFFIC) into the route folder for the route corresponding to this template.
Second, if the template unzips into a bunch of individual files, then you must carefully copy these files into the proper folders. Copy all .con files into the CONSISTS folder which is in the TRAINSET folder in the main train simulator folder. Next copy all .tfc files into the TRAFFIC folder which is in the route corresponding to this template. Next copy all .svc files into the SERVICES folder which is in the route corresponding to this template. Next copy all .pat files into the PATHS folder which is in the route corresponding to this template. Finally, copy all remaining files into the ACTIVITIES folder which is in the route corresponding to this template.
