Network Rail has released a dramatic video showing how flooding washed away part of the railway line linking North and South Wales.
Ballast was flushed away by rising waters at several locations.
I would like to thank passengers and all those affected by the closure of the line. The severity of the rain and flooding had a devastating impact and washed away enough of the track to make it very dangerous. We put in place immediate plans to reopen the railway as efficiently and as safely as we could.
