For obvious reasons, whether a line is rail-connected or not is important to many on this forum. However, most if not all lines get the bulk of their passengers by road. So whether a line is rail-connected or not has little to do with whether it counts as a premier-league line. The Bluebell was a premier-league line long before it made it to East Grinstead, for example.
The last time I travelled on the WSR (admittedly quite awhile ago), it was fairly easily accessible by local bus. Certainly no greater walk than say to the GCR.
In Switzerland, bus and train are seen as one coordinated public transport system. Why do so many rail enthusiasts in this country seem to regard buses with antipathy?
