One of my biggest gripes has been the poor provision of services on the Coastways from Brighton!
The West and East Coastway timetables pre 2020 were some of the best on the network, and did a brilliant job of combining connectivity, frequency and both faster and slower sevices. With only 2tph stoppers between Brighton and Chichester currently running, it is worse than the Sunday service (at least that provides a direct, albiet slow, service between Brighton and Southampton/Portsmouth).
Whilst it is good that services are being restored between Brighton and Southampton/Portsmouth in May, 2tph along an extremley populated area of the south coast doesn't cut it, and trains will be extremley busy, especially in school holidays. Why can't Southern at least restore some of the West Worthings, it would really help with overcrowding that will only get worse in the Summer.
On the mainline, there are no longer regular trains from Brighton to Clapham Junction on Monday to Saturday.
This is a byproduct of removing the London - Coastway splitters. Whereas before the Gatwick Airport rebuild, Brighton had 4tph to Victoria (2 Gatwick Express and 2 Southern (calling at Clapham Junction), since May 2020, the Southern services (xx:25/:55 off Victoria) to Brighton now run to East Coastway destinations, and the original Combined coastway trains that divided at Haywards Heath now run as one train to Littlehampton.
I agree that Brighton should have a connection to Clapham Junction, but the question is how can you achieve it? Do you add it to the Gatwick Express services (thus making them no-longer Gatwick Express)? Do you (as I think is best), remove Gatwick Express services and bring back the old Brighton express (Brighton-East Croydon-Clapham Junction-London Victoria)? Or do you make the Coastway trains split at Haywards Heath again reintroducing unreliability and shorter trains?
It is overall a shame that COVID and the DFT have effectively destroyed Southern's timetable, as the post 2018 Southern Timetable change was the best timetable and service provision I can remember on Southern's network.
