Eurostar trains are back up and running this morning, after all services between London and Paris were cancelled yesterday.
An unexploded World War Two bomb was found near the tracks in France.
It was safely dismantled by bomb disposal specialists and bosses say two extra services will run to deal with increased demand.
The bomb was discovered two metres underground during construction work on a bridge in the Saint-Denis area of the city in the early hours of the morning.

After moving the bomb into a hole, disposal experts managed to unscrew and then destroy its fuse.
French transport minister Philippe Tabarot said "the whole northern part of our country was paralysed" in the ensuing disruption, with almost 500 trains cancelled and 600,000 people in Gare du Nord affected.
Police in Paris described the 453kg bomb as "excessively dangerous" while head of the Paris bomb disposal department Christophe Pezron said it's the fourth one found in the area since 2019.
200 people evacuated
The disruption spread to the French capital's road network as bomb disposal teams worked at the site.
Police evacuated 200 people, including local schools, near a security perimeter set up around the bomb, while other residents in the area were asked to stay indoors.
First and Second World War bombs are regularly discovered around France but very rarely in such a densely populated area.
Official figures show that disposal teams have defused 700,000 air-dropped bombs and made safe nearly 50 million mines, shells and other explosive devices in France since the end of the Second World War.
