Guysborough is a county in northern Nova Scotia Canada, it a pretty bleak place in winter but lovely in summer. I think Stan may be lamenting the fact that no one can to Guysborough by train any more, or anywhere else in Nova Scotia for that Matter. The singer comes from Gusborough,it has made him the man he is, but for a number of reasons he can't go back. Sort of the theme of never being able to step into the same river twice. Just my take on it.
