Eurostar has warned travelers of significant delays and last-minute cancellations after a power supply problem disrupted services in the Channel Tunnel.

Eurostar has announced plans to run double-decker trains through the Channel Tunnel for the first time, marking a major upgrade for cross-Channel travel.
