Eurostar services were suspended on 2 March after a person was hit by a high-speed train in Kent.
British Transport Police and Kent Police were called to the incident at about 11.42am near to the line at Crismill Lane in Bearsted. The person was pronounced dead at the scene. BTP said it was treating the death as "non-suspicious".
Police closed the line between Ashford International and Ebbsfleet International, forcing Eurostar to cancel its services via the Channel Tunnel to and from London, France and Belgium.
A BTP spokesman said: "Officers are currently working to establish the identity of the person and how they came to be on the tracks. A file will be prepared for the coroner."
A spokesman from Eurostar said services were beginning to resume. However, some were still cancelled, causing chaos to hundreds of passengers. Trains affected included the 5.55pm from London to Brussels and the 5.56pm Brussels train to London. Here is the full list.
