To take advantage of the disruption caused by the rail strikes the line between Woking and Basingstoke will be closed on December 6 and 8-10 to repair a landslide.
Two of the four tracks on this stretch of railway will be closed while the work is taking place.
Trains will also need to be manually signalled by engineers using red and green hand signals, further reducing the number of services that can run. Thus only 3 of 16 trains per hour can run. This affects services to Salisbury (for Stonehenge) and Exeter, also to Winchester, Southampton and beyond.
