....So, do you accept that York-Guide Bridge-Chinley is valid?....
I cannot vouch for the mileages you quoted, but if it is the shortest route then yes it is valid, provided a sheduled passenger service operates.
....But surely you can consult the Routeing Guide, if you discover that a route you wish to take on the shortest route rule has no service (except in the opposite direction on a Friday morning)....
If we say there is no service on the route between Stalybridge and Guide Bridge, what is the shortest route by which a sheduled service runs?
If you are using the shortest route or direct trains you do not need to consult the Routeing Guide.
If the route you intend to take is NOT the shortest route or by direct trains, you need to consult the Routeing Guide.
....The easements can surely apply to the journey irrespective of whether or not it's the shortest route or a mapped route. The easements apply if you consult the RG. If on the shortest route there is nothing compelling you to read them or abide by them, though ATOC obviously think otherwise....
The easements only apply when you consult the Routeing Guide since the shortest route and direct trains are always valid. If you are using the shortest route or a direct train, why would you consult the Routeing Guide?
....No need for insults :roll: You are now agreeing that you can use the Routeing Guide to determine if there is an easement when doubling-back on a route that is not a mapped route!
Okay, I'll try to put this in very simple terms so even you can understand it.
The National Conditions of Carriage say the shortest route is ALWAYS valid.
The National Conditions of Carriage say direct trains are ALWAYS valid.
The National Conditions of Carriage say routes allowed by the Routeing guide are ALWAYS valid.
The Routeing Guide says you do not need to consult the Routeing Guide if you are using the shortest route or direct trains (why would you? You are using a valid route!).
The only reason you would use the routeing guide is if the route is not the shortest or on a direct train, why would you need to if the shortest route and direct trains are always valid?
So, we can safely say in your Bristol example that via Bristol is not the shortest route, nor is it using a direct train. Lets look at the routeing guide then.
Stapleton Road and Lawrence Hill are both part of Bristol Group
Oh look, it says the shortest route is the only one allowed by the guide...
...But wait a minute, there is an easement which helps us and now we can go via Bristol.
Does this mean via Bristol is the shortest route? Not a chance, it is just an easement
in the Routeing Guide which allows that route.
