The clue is in the branding- Chichester is clearly stated as one of the stopping places with the addition of the cathedral for good measure!
I did not expect them to operate to Southampton though!!
I anticipate Bognor-Littlehampton, Littlehampton to Brighton, West Worthing to Brighton and Southsea-Littlehampton will be 313s but unsure as to the rest.
A 377 could still cover from time to time though!
I'm all for it- more traction interest and I nver use toilets on trains lol
btw are they indicating on the timetable the traction? Do SWT do the same to indicate 444 or 450?
This is as far as I'm aware correct. Southern initially had a single Southampton-Brighton service (leaving at antisocial o'clock in the morning) planned for a 313 in the December timetable, on the basis that this train essentially had no through passengers along the entire route. Apparently through re-diagramming etc they now intend to operate this service with a 377, meaning the Southampton-Cosham line should be a 313-free zone. 313s are however still listed as agreed equipment which can be used on Soton-Brighton in case of times of disruption, etc.
Most routes planned for 313 operation are the shorter stopping services, although with apparently about 50% of Southern's departures out of Portsmouth planned for 313 operation they will turn up on many Portsmouth-Brighton services.
Traction type is not indicated on the timetables. I suspect that many services will be timed so that a 313 or a 377 could be used interchangeably if needed. As far as the lack of toilets go, well, it is certainly a downgrade but to be fair to Southern, a lot of the traffic on the coastway route is over shorter distances. I'd excpect the average passenger journey on the Coastway really is under 30 minutes.
A bigger concern is reliability and the effect 313s will have on this. Southern's coastway service punctuality is atrocious (they have averaged just 68% in the last month, for example, and 84% over the last year) and is just about the worst performing service group in the entire south of england.
Reliability is also poor, and the reliability stats mask the regular axing of scheduled stops and terminating short that goes on to try to recover the service.
I'm not confident that this situation will improve once 30-year old trains which were neglected by their previous operators start seeing widespread use!
