One in three commuters in the United Kingdom were delayed on their most recent train journey, according to new Which? research.

The consumer affairs organisation surveyed nearly 7,000 UK rail passengers, to find the best and worst train companies, and those with frequent delays.

The survey found that not only were 32 per cent of commuters delayed, but seven per cent of respondents said their last journey was delayed by 30 minutes or more.

Of leisure passengers, 15 per cent experienced delays – four per cent of these were delayed by 30 minutes or more.

Best and worst UK train companies for delays

Some 22 train companies were rated by Which? revealing the UK train companies with the most satisfied customers.

In November 2015, the group asked passengers to rate their train company on eight aspects of service, including availability of seating, value for money and overall condition of the train.

Each train company also got a customer score based on passengers’ overall satisfaction and likelihood to recommend the company to a friend. 

At the top of the satisfaction table, Grand Central got a customer score of 79 per cent, with the maximum five stars for availability of seating, punctuality, cleanliness of trains, reliability and value for money.

Abellio Greater Anglia (47 per cent), Thameslink and Great Northern, and Southeastern (both with 46 per cent) were the worst-scoring companies.

Which also asked passengers to name the improvements they’d like to see on trains. 

Most wanted extra carriages at peak times to guarantee seats. 

Better on-board facilities, such as clean working toilets that flush properly, were also a popular request.
