GTR have released a consultation document which includes possible service changes across the franchise (http://www.southernrailway.com/your-journey/timetable-consultation).
I have created this thread so that we can get a better understanding (than was given in the consultation document) of the effects of the proposals, so that we can work together to give GTR better feedback and perhaps develop alternative solutions (where the consultation permits) that we can show GTR.
The proposals which I think may have complicated interconnected effects in terms of the timetable and diagrams are:
I will now analyse the effects on the diagrams of each proposal:
Cut peak Lewes-Seaford line services to 2tph rather than 3tph to improve reliability on single track sections by either cutting the services which split/attach with Victoria services or reducing the Brighton-Seaford service from 2tph to 1tph during the peak
Cutting the Victoria train would mean the Victoria service would have a better journey time beyond Lewes via Polegate, would be longer as far as Eastbourne and would be more reliable. Cutting the Brighton-Seaford service level would result in two trains being required to operate the rather than three (since the 37 minute Brighton-Seaford time makes the service too much for one train to cover) or the service to be interworked with another service.
Increasing the frequency of the Brighton-Lewes shuttle from 1tph to 2tph
This service takes 15-17 minutes end to end and is presently operated using one train. Doubling the frequency would require two trains or it could be interworked with another service. This service could perhaps be interworked with a 1tph Brighton-Seaford service during the peak using 4 trains. The same number of 313s as is presently used for the Brighton-Lewes(-Seaford) service.
Running the Brighton-Ore services non-stop between Brighton and Falmer
This obviously reduces the journey time.
Terminating the hourly Victoria-Ore services at Hastings with an hourly Southeastern Charing Cross-Hastings service being extended to Ore
This would mean that the Victoria service would arrive at Hastings 13 minutes before it heads back to Victoria (if the current timings are maintained). The Brighton-Ore service which this service is presently interworked with has Brighton bound service leave Ore just 5 minutes after the service from Brighton arrives. Therefore implementing this proposal in isolation would save an EMU and the service could be interworked with the Brighton-Lewes service and/or combined with the proposal to run the service non-stop between Brighton and Lewes to provide enough reliability for the Brighton-Ore service.
Splitting the hourly diesel Brighton-Ashford service into an electric and a diesel service which both terminating at Eastbourne or Hastings
Splitting the service at Eastbourne might allow something similar to the present timetable to operate with a cross platform connection at Eastbourne. The most used section of the service was shown to be Bexhill-St Leonards Warrior Square, but the trains not running beyond Eastbourne and the Brighton-Ore service running non-stop between Brighton and Lewes might transfer demand to the service from Ore. Splitting the service at Hastings has the complication of its present Brighton-Hastings time being 64 minutes. The service would therefore require 3 trains or it would need to be interworked. The consultation states that the Ashford-Brighton journey time would be extended by around 27 minutes with that time requiring changes at Hastings and Lewes. This fact suggests that GTR would interwork the service at the Brighton end with one of the services which I have already stated could benefit from interworking. GTR are clearly prioritising the saving of running an extra EMU compared to the 23 minutes (if one assumes a 4 minute connection at Hastings) of Brighton-Ashford journey time and hiding this fact from the public.

I would think that the proposal to split the Brighton-Ashford service at Eastbourne could be improved by having both services call at Hampden Park so that the subsequent connections could improve the service reliability and/or journey time for non-Eastbourne passengers capable of climbing a bridge. It would also give the local area a better service.

- Running the Brighton-Ore services non-stop between Brighton and Falmer.
- Terminating the hourly Victoria-Ore services at Hastings with an hourly Southeastern Charing Cross-Hastings service being extended to Ore. This is suggested to improve reliability by removing the interworking between the Victoria-Ore and Brighton-Ore services.
- Splitting the hourly diesel Brighton-Ashford service into an electric and a diesel service which both terminating at Eastbourne or Hastings. This is suggested to solve the overcrowding between Brighton and Hastings which according to the graph GTR showed peaks between Bexhill and St Leonards Warrior Square. GTR also want the public to potentially suggest other ideas to solve this problem which do not require extra diesel stock or doubling up 171s at stations which don't have long enough platforms for passengers to get in/out of both sets.
