Not on the Windsor side. Complete recast there.
The actual times (throughout the network) appear to be completely changing too, so while the frequencies are by and large the same, it's the first time since 2004 there's been a big change.
Certainly one of the biggest changes since the early 80s.
The 2004 timetable has been remarkably static, lasting 14 years with only minor amendments. Contrast that to the late BR and early SWT years when we had major changes in 1989, 1997 and 1999 and signficant changes on some lines - if not all - in 1988, 1990, and just about annually from 1992 to 1994 if I remember right. While the 1989 and 1990 timetables were major improvements, the last period was a depressing one; a recession-led decline that resulted in only two trains an hour south of Guildford in the 93/94 timetable, one fast (81) and one all stations (82) - but does anyone then remember the somewhat-bizarre Waterloo-non stop via Cobham-Guildford-all stations to Haslemere that ran during the 1994/95 timetable every hour off-peak (allowing the '82' to miss out Milford and Witley)?
