In the Permitted Route Falkirk to Glasgow thread, PaulLothian asked
In 1996, the first National Routeing Guide contained a small list of 12 Local Easements which were just that, relaxations of Routeing Guide rules to allow journeys that strict adherence to the rules would forbid. Unfortunately, a few years later the train companies started to add to the list a large number of rules which were not Easements at all. They were, and are, extensions of Routeing Guide rules to prohibit journeys that strict adherence to the rules would allow.
One example is
The train companies then played fast and loose with the English language by calling these prohibitions Negative Easements and listing them in a single document called Easements.
These so-called Negative Easements continue to proliferate. Only yesterday, more were added. See the Easements thread.
But these are no longer the only types of Easements. The National Routeing Guide Data Feed Specification tells us that there are now seven types of Easement:
Many of the Easements make very little sense to the passenger. For example, yesterday this rule was added:
Suggestions for sorting out this mess would be very welcome.
The 12 original, genuine Easements were:
and"Customers travelling between Glasgow Queen Street and Edinburgh may not travel via Larbert. This easement applies in both directions" ...
what is the standing of the easement?
why would there be an easement preventing use of a Permitted Route?

But this particular rule has limited application. For example, it does not seek to restrict customers travelling between Glasgow Queen Street and Haymarket, who may continue to travel via Larbert.Easement 300209
Customers travelling between Glasgow Queen Street and Edinburgh may not travel via Larbert. This easement applies in both directions.

But these are no longer the only types of Easements. The National Routeing Guide Data Feed Specification tells us that there are now seven types of Easement:
- Local easement
- Map easement
- Routeing point easement
- Doubleback easement
- Fare route easement
- Manual easement
- Circuitous route easement
Many of the Easements make very little sense to the passenger. For example, yesterday this rule was added:
The day before yesterday, when this Easement did not exist, whenever we travelled from Burton On Trent via Chesterfield, we went via Derby. It's the only sensible way to go! The value of telling us that we're allowed to do that is not immediately obvious.Easement 700217
Customers travelling from Burton On Trent via Chesterfield may travel via Derby. This easement applies in both directions.
