An investigation is underway following the discovery of a body at the side of a rail track near Slateford.
The body was found just before 9am on the Glasgow Central to Edinburgh line causing a delay to services.
Emergency services were called to the scene and services are likely to be cancelled or heavily delayed throughout the day.
A spokeswoman for train operator ScotRail said: “Services between Edinburgh and Glasgow Central via Shotts are being disrupted.
“Customers with valid tickets from Glasgow Central to Edinburgh can use tickets to travel on alternative routes from Glasgow Queen Street to Edinburgh via Falkirk High and Airdrie.
“Customers travelling to or from Livingston South station with valid tickets can also use Livingston North as an alternative.
“The train operator urged customers to check before travel by visiting its website at scotrail.co.uk.”
A spokesman for British Transport Police said enquiries were at an early stage.
