A woman and young child have died after being hit by a train in Slough, Berkshire, in "suspicious circumstances", police have said.
Police were called just before 09:45 BST and the station is currently closed.
A British Transport Police spokesman said they had not yet identified the victims and could not at this stage confirm the age or gender of the child.
They are appealing for witnesses to the incident.
A South Central Ambulance crew pronounced the two people dead at the scene.
The train is being investigated by police
A British Transport Police spokesman said: "The incident is currently being treated as suspicious. Officers are working to identify the deceased and a full investigation has been launched."
The train, the 08:41 from Bedwyn, has now resumed its non-stop service to Paddington.
