The main rail line from Edinburgh to Glasgow has been forced to shut after torrential rain and severe flooding in parts of Scotland.
The Winchburgh tunnel in West Lothian has flooded, resulting in passengers on five trains being trapped for several hours.
ScotRail has tweeted that there are still severe problems there with water sitting two feet above the rails.
The issue is continuing to affect rail services across the central belt. ScotRail said engineers had been working through the night to pump water from the tunnel following the deluge on Wednesday.
Footage released by ScotRail shows the impact the recent torrential rain has had on the the rail line. The Network Rail team remain on site to pump as much water out as possible.
