Many Southern train services have been suspended due to severe weather overnight.
Several lines are suffering from a combination of flooding, blockages from fallen trees, power supply failure or landslides.
A Southern spokesman said: “The stormy weather overnight/this morning (December 24) has caused considerable difficulties for our rail network and the surrounding road network. As a result,
We are currently trying gauge the full extent of this damage and the prospect for operating services safely.
“Currently we are working closely with our colleagues in Network Rail to prioritize the clearing and proving of routes to be safe before trains can operate.
“This means that many train services remain suspended until this work is complete and we do not expect this to happen until much later this morning.”
