New timetable for Southern Rail
Commuters have faced delays on the Southern Railway network on the first day of the train company's new reduced timetable.
Passengers vented their frustration on the firm's Twitter feed as services failed to arrive on time on Monday morning.
Southern Railway said the interim move, which has seen it cut 341 trains a day for a month, was aimed at making services more ``resilient''.
A spokesman said: ``Ninety-five percent of trains are running on time or within five minutes against a revised timetable and there has been no reporting of overcrowding issues.''
He added that one Southern service had been cancelled between Horsham and London Victoria.
A Thameslink train to Bedford was also cancelled and one commuter's photo pictured display boards showing just a handful of trains listed as running on time, including those bound for London.
The firm previously apologised to passengers for weeks of disruption and pressed ahead with the timetable changes despite warnings that they could have a ``devastating'' impact.
Southern, owned by Govia Thameslink Railway (GTR), blames high levels of staff sickness as well as industrial action by the Rail, Maritime and Transport union in a dispute over the role of conductors.
Southern's passenger services director, Alex Foulds, said when the changes were announced last week that the cuts would mean ``a better, more consistent service''.
