There was a cable fire around 7am this morning just outside Clapham
Junction. All Southern services used the Up Slow and Down for about and
hour and then the fasts were re-opened. Southern services took another
hit with a track defect at Norwood and a signalling problem at Tulse
Hill.

Gatwick Express reduced to half hourly and South West Trains instigated
an emergency timetable of sorts (the usual story of Hampton Court
becoming a shuttle etc...) and I do wonder why Southern don't have a
similar system of reducing the number of trains trying to reach London
when these major incidents occur.
