A spokesman for Eurostar said: “They obviously had to stop and check the train was safe to carry on and that caused residual delays on the line.”The wild boar in the area can “take it upon themselves to roam from their area onto the track”, a spokesman said.Customers complaining about delays to their journeys were told on Twitter there had been “an incident involving a wild boar” and they would be “on the move shortly”. Wild boar are related to domestic pigs and have thick, bristly coats. They weigh around 20 stone – although some males can reach double that – and live for approximately 30 years. The train later arrived safely at the Gare du Nord in Paris. Delays on Eurostar. Leaves on the line? No. A wild boar.
