That's really not a fair comparison.

Virgin Trains, running only long-distance intercity journeys, is compared to London Overground, which runs trains within London every 4-6 minutes for commuters. I'd also guess the average Which? reader is much more likely to rely on a train for work if they live in the south east.

If we compare local services, the south east is much better: much more frequent service, newer trains, generally staffed stations, better value fares within London.

If we compare long-distance services, the trains often start or end in the south east anyway.
