The Great Flood of 1968 was a flood caused by a pronounced trough of low pressure which brought exceptionally heavy rain and thunderstorms to South East England and France in mid-September 1968, with the worst on Sunday 15 September 1968, and followed earlier floods in South West England during July.[3]
This was likely the severest inland flood experienced in the Home Counties during the last 100 years.[1][4]
On 15 September 1968, the 9:50 Charing Cross to Hastings was diverted along the Edenbridge line, but was surrounded by flood water at Edenbridge railway station. 150 passengers spent 12 hours stuck on the train.
France
In the first seven hours of 15 September 1968 three inches of rain fell on Nice. In Toulon a cyclist was killed by an electricity cable that had fallen into the flooded road. The wine harvest was seriously damaged.[6]
