Heavy rain and strong winds caused travel disruption in several parts of the UK as Storm Gareth moved east.
Northern Ireland was the first area to be affected, while parts of Scotland and north-west England experienced flooding.
National Rail said there was disruption on various train lines in Scotland, Wales and northern and eastern England.
A yellow Met Office weather warning of heavy rain is in place for Thursday.
BBC Scotland Weather said winds had reached storm force across Argyll, with a gust of 75mph at Machrihanish.
The strong winds brought trains between Durham and Newcastle to a halt until 09:00 GMT after overhead electric wires were damaged, impacting LNER, CrossCountry, Northern and Transpennine Express services on Wednesday.
Virgin Trains services between Manchester Piccadilly and London Euston, and some trains between Glasgow Central and Preston were also cancelled.
Meanwhile, P&O Ferries said Wednesday morning crossings between Dover and Calais were delayed by up to 90 minutes, which resulted in long delays for motorists on the M20 in Kent.
Police implemented Operation Stack - allowing lorries waiting to cross the Channel to park on closed sections of the motorway - between junctions eight and nine on the Dover-bound carriageway from 12:20 GMT with all other traffic diverted to other routes.
