Southern Rail timetables were thrown into chaos again this morning after it cut one quarter of its trains as a ban on overtime by union Aself kicked off this morning.
The union is in a long-running dispute with the train company over the role of train staff as the business attempts to roll out driver-only trains.
The revised Southern timetable will affect commuters in Kent, Sussex, Surrey and Hampshire.
Travellers trying to get to Gatwick from Brighton will also be affected, as there will be no off-peak trains between the airport and the seaside town. There will be a limited service during peak times.
Direct services between London and Southampton, and London and Portsmouth, have been axed. Passengers will instead have to change trains. There are also no trains between East Croydon and Milton Keynes via Kensington Olympia.
Mick Whelan, Aslef union's general secretary, said:
The ban reflects the total loss of trust and goodwill between train drivers and the company.
