For years, my wife and I have traveled from NJ to vacation in the Burlington area, mainly because of the magnificent bike path that runs along and into Lake Champlain, bike ferry and all. And as a rail trail advocate, it has always been my opinion that such trails are designed ONLY for non-motorized travel (wheel chairs excepted for good reason). Whenever I read about the benefits of railtrails, number one is usually exercise and good health. And I can't see the benefit of having people avoid those benefits by getting on a machine on what is supposed to be a SAFE, OFFROAD path. And, of course, motorized vehicles shouldn't be on rail trails for safety reasons. So, no, I don't think segways belong on rail trails, just like ATVs don't belong on rail trails. Kind of defeats the purpose, doesn't it?!
