Train passengers returning to work after the summer holidays are facing travel disruption today because of a strike in the long-running dispute over guards on trains.
The strike by members of the Rail, Maritime and Transport union on South Western Railway has been going on since Friday - and will hit services until Tuesday morning.
Some trains are cancelled, others replaced with buses and fewer services are running into London Waterloo, the country's busiest station.
It's the 35th strike on South Western Rail over the past two years.
SWR said it planned to run just over half its normal timetabled service over the course of the strikes and will try and introduce extra services wherever possible.
