It seems that SWT's relationship with bus companies in general has not been carried forward with SWR. Often we see SWR saying that if you wish to use buses, by which they mean service buses, there's no ticket acceptance. WRT the Rowlands Castle incident I agree, that at least 12 hours before, SWR were warning of significant disruption which one might have assumed would be enough time to source replacement buses, despite the high utilisation of the surplus drivers and vehicles on school contracts at that time of day. Moreover why could they not have run the down services originating from Waterloo/Woking/Guildford to reverse at Petersfield?
