https://www.bbc.co.uk/news/uk-england-45864908Rail passengers have been delayed on more than half of all services from 10 of Britain's busiest stations this year, research has found.
Manchester Oxford Road took the "undesirable crown" of performing worst, according to Which?
It found York, Gatwick Airport and Birmingham New Street all saw less than 40% of trains arrive on time.
A rail commuter in London said people face "a daily battle simply to get from A to B".
Which? said even small delays could have "a knock-on effect" on passengers' ability to complete their journey.
The consumer group looked at services at the 10 busiest stations in London and the 20 busiest outside the capital from the start of January until the end of September.
Dire knock-on effects
Using data from performance tracking site On Time Trains, the group found 68% of services were delayed at Manchester Oxford Road, rising to 77% during peak times.
The city's two largest stations, Piccadilly and Victoria, also suffered a high percentage of late services.
A Which? spokesman said the "timetable chaos earlier this year", caused by the implementation of new schedules by train operator Northern, had had "dire knock-on effects for [Manchester] passengers' personal and professional lives".
The data also showed the percentage of service cancellations at each station.
London King's Cross saw the highest rate of cancellations - 6% - while Manchester Oxford Road and Gatwick Airport were once again among the worst performing.
