Your route appears to be worst impacted as a result of this but at least they've reacted to providing an earlier service next week and in due course the normal service to Victoria will be restored.
My route appears to be worst impacted because it seems to be the only route in the whole Southern network that doesn't have any evening trains on a Saturday evening (something that in itself is not justifiable and that I have tried lobbying against). Except that in last year's lockdown timetable it did have a Saturday evening shuttle service from Dorking to Horsham because the COVID lockdown timetable (a modified weekday timetable and not a modified Saturday timetable who's only actual purpose was to provide for major signalling works in the Clapham Junction area over xmas and not to cope with train crew shortages caused by COVUD) was in force from Monday to Saturday.
The problems on my section of line comes from having an existing unfit for purpose Saturday service with no evening service and then using that Saturday service timetable as the basis of the alleged Omicron staff shortage emergency weekday timetable, something that was never envisaged as being the purpose of that timetable when it was created.
The stuff about it taking ages and ages to come up with new route diagrams etc for train crews is all baloney as far as I am concerned as Southern/GoVia already have a Saturday timetable with all of those things in place so as long as they run that whole timetable in to London Victoria. Extra work is only created by altering the Saturday timetable services to terminate them at London Bridge so you would have thought they would want to change all services back to London Victoria ASAP.
But no they now seem to have a love affair with running man of their services in to London Bridge for as long as possible so I can't see why that's the case unless Network Rail is continuing their signalling improvement project on the QT until some date or other well in to February..........
