Angry commuters waited for over an hour on crowded train platforms as scores of trains were cancelled on Monday morning, the first working day of the new timetable across four major operators.

Every train run by the UK's busiest franchise, Govia Thameslink Railway (GTR) - which consists of Southern, Thameslink, Great Northern and Gatwick Express - was rescheduled from Sunday.

Officials at GTR were unable to give The Telegraph the number of trains cancelled on Monday morning, but most stations in and around London this morning listed many cancelled services from those operators.

Those who managed to cram on to a crowded train faced having their services cancelled while they were on board as drivers were not available in London.

Others had their services diverted, with at least one train to Gatwick terminating at St Pancras International.
