Rail commuters have slammed the new winter timetable after dozens of services were cancelled or delayed.
The new timetable, which came into force on Sunday but was trialled for the first time by many on Monday, promised more services and shorter journeys, while a number of new routes were added.
But passengers travelling on Monday morning complained of services being heavily disrupted, slamming the timetable for having "no room for common sense".
Staff shortages, signalling problems, a landslip and ongoing industrial action were among the issues affecting the network across the country.
Many commuters have taken to social media to express their frustration - saying they deserve better, that it 'wasn't good enough' and that 'nothing changes'.
One Twitter user said: "@GWRHelp 90% of trains at Maidenhead to London are cancelled yet in the last 10 mins I’ve watched 2 half full trains pass straight through without stopping?
"Does your new winter timetable have no room for common sense?"
Another added: "Great start to the new timetable by @northernassist my train cancelled and every other train between 7:30 and 9am is delayed. We deserve so much better."
Some early-morning trains operated by Northern Rail were cancelled due to a shortage of drivers, while TransPennine Express have several cancellations listed for throughout the day due to a shortage of crew or train faults.
Great Western Railway passengers were being warned to expect cancellations, delays and fewer trains between Reading and London Paddington due to a fault with the signalling system at Maidenhead.
Due to strike action by the RMT union, travellers on South Western Railway (SWR) have been warned of fewer trains, earlier finishes and some replacement buses throughout December.
Elsewhere on the SWR network, a landslip between Epsom in Surrey and Motspur Park in south-west London left all lines between the two stations blocked.
One Twitter user said: "Oh dear @ScotRail. Another Monday morning disaster on the first proper day of the new 'improved' timetable. Train cancelled. And the next two significantly delayed. #NotGoodEnough."
Another added: " @tfwrail Had to catch the earlier train because of your timetable changes and then the train is 20 mins late! Nothing changes."
The Rail Delivery Group (RDG) previously promised more services, shorter journeys and new routes becoming possible across the country under the new timetable.
"These would include the first non-stop trains between London and Bristol in decades, plus 1,000 extra services each week.
RDG said the industry had put "years of work into drafting, consulting and planning" for the changes.
Robert Nisbet, Director of Nations and Regions at the RDG, said: “There are a number of unrelated incidents affecting a small proportion of journeys this morning, and the train operators involved are working with Network Rail to minimise disruption.
"While the vast majority of services are running as planned, we are keeping people moving and we are sorry for the inconvenience caused.
"More services are running than before the timetable change and passengers will benefit from 1,000 more services a week.”
Train timetables are changed twice a year, in May and then in December.
The timetable change of May 2018 led to weeks of chaos for travellers, and passenger watchdog Transport Focus said travellers would be hoping for a smoother introduction with the latest changes.
