The "info" file is just there to help load the session list faster. You really only need the .xml file. I downloaded this session to both the Barstow trains folder and the World Saves folder and both of them showed up as separate sessions. I noticed that when I told it to save, it did not include the file extension in the name of the file but told me right below the name that it was going to save as a .xml file. Maybe some exact details about the steps you are taking to download and save the file?
I hope this helps.
