A murder inquiry has begun after a man was stabbed to death on board a train in Surrey.
British Transport Police (BTP) said the man was stabbed on board the 12:58 Guildford to London Waterloo service.
Rail services have been suspended and part of Horsley railway station remains cordoned off.
The London-bound train is currently being held at the station, which is in the village of East Horsley and emergency services remain at the scene.
A BTP spokesman said the man suffered a fatal stab wound.
Rail services are suspended between Guildford and Effingham Junction.
South Western Trains have tweeted that the line towards Waterloo is blocked.
A statement on the SWT website said: “We have been informed that the police are dealing with an incident between Clandon and Horsley.
“Until the police have carried out their investigations the line between Guildford towards Effingham Junction is currently blocked.”
Replacement bus services are being brought in.
