A number of rail operators have closed routes and cancelled services due to flooding caused by storm Dennis in the UK, with bridges closed and roads submerged in many parts of the country. Drivers and rail passengers have been urged not to travel unless necessary. Passengers with Great Northern, Thameslink, Gatwick Express and Southern Rail and anyone travelling on Great Western Rail into and out of Devon and Cornwall has been advised against non-essential journeys. Flooding has blocked lines between Ash and Guildford, Sway and Brockenhurst, and the lines between Exeter St David’s and Barnstaple, Yeovil Junction and Taunton.
