Groupe Eurotunnel SA said passengers unable to travel through the Channel Tunnel after a fire yesterday can all make their journeys today after one-third more slots were granted to express-train operator Eurostar International Ltd. Eurostar will be able to run about 40 services, compared with 30 on a normal Sunday, as the maximum number of trains are squeezed through the one open tube. The second tube, where the fire occurred, should open later today or tomorrow morning, Eurotunnel spokeswoman Fabienne Lissak said by telephone.
