Figures show Southeastern is the second worst for delays bringing misery to south east London and north Kent commuters.
A Which? Survey of 7,309 passengers on journeys travelled in the year up to last November highlighted the dissatisfaction with services.
When passengers were asked about their last journey 33 per cent of Southeastern passengers reported a delay – the second worst overall.
Southeastern's overall satisfaction rate was just 44 per cent, compared with Grand Central at the top of the list receiving 76 per cent.
Areas covered included the availability of seating, punctuality, value for money, and the cleanliness of toilets and the carriages.
The worst performer was Southern with 39 per cent of commuters reporting a delay, and c2c the best with only 14 per cent experiencing a hold-up.
Martin Abrams, public transport campaigner for the Campaign for Better Transport, said: "The Which? Survey paints a bleak picture of expensive fares, frequent delays, overcrowded, dirty trains and poor communication from train companies to passengers.
"It is very notable that some of the busiest train routes around London and the South East are also regarded as offering the worst value for money."
Southeastern was the third best for letting passengers know their rights regarding delays with 31 per cent saying they were told they were entitled to a full refund on their last journey, compared to the best scorer London Overground with 38 per cent.
But the train company hit back at the results, issuing a statement saying: "We are disappointed with the scores published in today’s Which? report.
"The survey took place in November 2014 and reflects a difficult autumn period for our passengers, during which their journeys were affected by a broken crossing at Lewisham and a number of signalling problems.
"These incidents saw our Public Performance Measure dip below 83 per cent.
"We are committed to improving performance through a robust new timetable introduced last month which has already seen punctuality improve.
"In March, we will start a deep cleaning programme of all our trains that will improve the travelling experience on Southeastern."
