I share a train with Claude above, so theoretically no impact in the morning, although there's now an additional service running direct to London Bridge, which is nice. Coming home it looks worse on paper - timetabled to leave 15 minutes later which is a pain, but then the previous service was always c10 minutes late, so if the new 18.03 runs to time then I'll be happy. There's a new 17.03 too, which could be useful for those early getaways.
Overall I'm a bit meh. We shall see.
