Snowfalls of up to 10-15cm have led to train services being cancelled on a number of routes in the south east today. However, the worst of the weather affected Sussex and Kent. There were some delays north of London, but in general services in Buckinghamshire, Hertfordshire and Essex kept running.

Southeastern services were cancelled between London and Folkestone/Dover, London and Ashford, Strood and Maidstone West, Paddock Wood and Tonbridge, London and Sevenoaks, Tunbridge Wells and Hastings, and London and Canterbury. High Speed domestic services between London and Ashford were running, however.

A little further west, Southern reported cancellations between Redhill and Tonbridge, and delays on several other routes. North of the river, West Coast services run by Virgin and London Midland were running late, and First Capital Connect also reported delays, particularly south of Blackfriars. London to King's Lynn services were running in two sections, with a change of train at Cambridge. National Express East Anglia decided yesterday that it would run a reduced timetable today, said Network Rail. Delays of up to 40mins were being reported in various parts of East Anglia, but all routes stayed open.

There were delays of up to 60mins on the East Coast Main Line, where the problems were being blamed on train faults and signalling difficulties as well as the weather itself.

Network Rail said all main strategic routes had been kept open by snow clearing and the de-icing of conductor rails overnight. In this morning's peak, 70% of trains were officially on time, which for most trains in the south east means less than 5mins late at the final destination.
