The current 5th train from Hounslow to Waterloo via Brentford in the morning will become the 1st train on the new timetable. Considering the other 4 trains are busy I think it's a pants service and makes no sense. DfT have a lot to answer for.Having a very quick look at weekends the only change I can see is the withdrawal of all Hounslow loop services as per weekdays. Apart from that the timetables appear to remain as per Dec 2019.
Also the timetables are dated until 13th May.
Are there any other changes I've not noticed?
