I've downloaded a freight timetable for the Loetschberg route which details start and end points (some in Netherlands). It comprises a pdf and an xl file. I download each as it is published so the latest that I have is from 09-2011. I get it from www.bahnonline.ch where I am subscribed to their newsfeed. The latest is available at http://www.bahnonline.ch/wp/124/guterverkehrsfahrplan.htm#more-124
