Some more updates have been made to the routeing guide.
These were either published on Thursday or Friday, but I'm not sure which off-hand.
New dataset IBRG0383 published 23 October 2015 to correct a date error in IBRG0382 (which was sent to data systems on 22 October 2015) contents that have changed are listed below under the reference IBRG0382. The electronic data error sent to Journey planners related to Easement 700598, where an end year date has been included which was incorrect.
New dataset RJRG0382
Following a review of permissions on the Great Western Mainline, in preparation for major engineering works associated with the electrification of the route, and in particular the impact on routes through the Severn Tunnel. To harmonise the map permissions of Swindon with other relevant Routeing Points, and to allow travel to/via Newport South Wales avoiding the Severn tunnel
Map sequence added
Bridgend (BGN) and Swindon (Wilts) (SWI) - added sequence 'LW'
Cardiff Central (CDF) and Swindon (Wilts) (SWI) - added sequence 'LW'
Newport S.wales (NWP) and Swindon (Wilts) (SWI) - added sequence 'LW'
Pontypridd (PPD) and Swindon (Wilts) (SWI) - added sequence 'LW'
SWANSEA GROUP (G38) and Swindon (Wilts) (SWI) - added sequence 'LW'
Swindon (Wilts) (SWI) and Whitland (WTL) - added sequence 'LW'
These adds mapped routes via Gloucester, where the journeys have previously only had mapped routes via Bristol and the Severn Tunnel on the SB map.
Following review of map permissions between routeing points on the West Coast Mainline and in the east midlands, the following changes have been made.
Map permissions for Milton Keynes to Leicester now include via Bedford, as journey planners will not show journeys via London as all fares are priced on Fare route 00700 Not Via London.
Map sequence added
Bletchley (BLY) and Leicester (LEI) - added sequence 'EN+PR'
Map sequence removed
Bletchley (BLY) and Leicester (LEI) - removed sequence 'EN+EM'
This removes mapped routes via Corby.
It adds ones via London (for those not using "Not via London" tickets).
Kettering (KET) and Northampton (NMP) - added sequence 'EM+EN'
Kettering (KET) and Northampton (NMP) - removed sequence 'MI+BP+WM'
The routes on EM+EN are completely different to those on MI+BP+WM, but this has no effect on ticket validity.
There are two stations associated with Kettering (Corby and Market Harborough) and two with Northampton (Long Buckby and Wolverton).
All tickets between these stations are routed "via Bedford".
EM+EN contains routes via Leicester, but none go via Bedford.
MI+BP+WM contains a route via Bedford, but this follows the shortest route to Kettering (or its associated stations) from Northampton or Long Buckby.
Northampton fails the fare check for Wolverton-Kettering and Wolverton-Market Harborough.
No fare check can be completed for Wolverton-Corby as there is no fare data for the route in ATOC's
NFM64 file. I have not yet been able to find out how to determine which routeing points are valid in this situation, but ATOC's
routeing point calculator claims Northampton is not a valid routeing point anyway.
In summary, it removes mapped routes which were already invalid, and adds one which was already valid. I do find it easier to calculate mapped routes than the shortest route, though.
Kettering (KET) and Nuneaton (NUN) - added sequence 'MI+CN'
Kettering (KET) and Nuneaton (NUN) - removed sequence 'EM'
This removes a mapped route via Corby.
Kettering (KET) and Rugby (RUG) - added sequence 'MI+CN+ES'
This adds a route via Bedworth.
It also makes the shortest route from Kettering to Rugby a mapped route. This goes via Leicester and Nuneaton.
Leicester (LEI) and Milton Keynes Central (MKC) - added sequence 'PR+EN'
This adds mapped routes via Bedford.
Bedford (BDM) and Coventry (COV) - removed sequence 'TV'
This removes the direct line from Rugby to Coventry as an option for a "not via London" ticket.
Following review the easement restricting the use of fare route 00000 Any Permitted tickets on the new Oxford Parkway to London Marylebone services, the follow change has been published. This will allow the use of Islip and Bicester Village Any Permitted tickets, but not Oxford or beyond. The validity will be amended on commencemnet of through services in Spring 2016.
700598: Following the introduction of the Chiltern services from Oxford to London Marylebone; tickets on Fare route 00000 Any Permitted from or via Oxford, Oxford Parkway, Islip or Bicester Village to London or beyond will not be valid on the new services via High Wycombe and will remain valid only via Oxford. this negative circuitous route easement will apply in both directions.
Oddly enough, the change list includes the old version of the easement rather than the new one. The new one is:
700598: Following the introduction of the Chiltern services from Oxford Parkway to London Marylebone,and until Chiltern operate direct through services from Oxford to London; tickets on Fare route 00000 Any Permitted from or via Oxford to London or beyond will not be valid on the new services via High Wycombe and will remain valid only via Reading. This negative circuitous route easement will apply in both directions.
The main changes from this are that it comes into effect sooner, and only affects journeys from, to or via Oxford.
To make the following easement operate in all journey planners, it has been altered from a doubleback to a local easement. The text is unaffected.
700600: Customers from Islip travelling to or via Haddenham & Thame Parkway may doubleback between Islip and Oxford Parkway. This positive local easement applies in both directions.
The previous version of the second sentence called it a "positive doubleback easement".
The electronic data in this easement has been amended, to exclude travel to the east of the West Coast Mainline south of Penrith. The text has been changed to reflect is.
300234: Customers travelling from Appleby or Kirkby Stephen to Penrith and beyond may travel via Carlisle. But they may not travel on journeys that include any of the following locations, Hellifield; Blackburn; Bolton; Salford; Manchester or Stalybrdge,This easement applies in both directions.
The second sentence is new. I'm not sure that it means someone with (say) an Appleby-Hindley ticket with route "Not Preston/Liverpool" is unable to travel via Hellifield, is unable to travel via Carlisle and Hellifield, or is unable to travel via Carlisle and Hellifield on a route which would not be allowed without this easement.
