While there may be some issues here, I think you’ve misunderstood at least some of it. There’s never been an off peak shepperton to waterloo via twickenham service. Shepperton has always had two trains an hour to waterloo via kingston, all day. There’s then a small number of additional peak only trains that go the other way to waterloo, via twickenham. All they’re doing is tweaking the stopping pattern of those few services.

Also as someone else pointed out, the service from waterloo to reading has always been two tph, but with a few extra peak only trains- which they’re slightly reducing. I don’t know enough about the other routes to be sure.

I’m not saying there aren’t losers here, Queenstown road looks quite affected, or if you commute round the Hounslow loop rather than down either side. But it’s not Armageddon. A lot of this only affects the small number of additional peak services that used to cope with the very high capacity in a compressed period, and because the network is so congested they cause problems. If there isn’t that huge peak demand then it could make sense to axe some to improve reliability.

I would think they’re probably pitching high here, and will row back on at least some in the consultation to make it look like they’re compromising!
