Post-pandemic frequency cuts of off-peak suburban trains

Southeastern has announced that it will restore the frequency of the Victoria – Orpington line to every 15 minutes December this year.

We will also increase off-peak and evening stopping services between Victoria and Orpington via Herne Hill to provide trains every 15 minutes – enabling a ‘turn up and go’ Metro timetable.

However, there are still a number of routes where the service is still basically unusable during off-peak (worse than every 15 minutes) after the COVID cuts, for example:

• Victoria – Selhurst – Sutton (previously every 15 minutes, now every 30 minutes)
• Hounslow loop (between Waterloo and Barnes, previously every 7 / 8 minutes, now it is 8 / 22 minutes at Wandsworth Town)
• Waterloo – Epsom (via Wimbledon) (previously every 30 minutes to both Guildford and Dorking, giving every 15 minutes between Waterloo – Epsom, now halved to useless frequency)
• The Thameslink line between Kentish Town and Orpington, giving Blackfriars – Bromley South 4 trains per hour previously when combined with the Sevenoaks service
• Northern City line (previously every 15 minutes on both Hertford loop and mainline via New Southgate, combined to provide 8 trains per hour from Moorgate, but now halved to useless frequency north of Alexandra Palace)

I would like to know how these service cuts have affected Londoners in general. Are people who live in affected region no longer travelling by trains, and resort to using private transport instead? Have you been put off from visiting family / friends in these regions because the train service is too bad?
