A power supply failure in the Channel Tunnel caused significant travel chaos, leading Eurostar to suspend services between London and mainland Europe during the busy New Year travel period. Passengers faced hours of delays, some stranded overnight on trains without power, heating, or functioning toilets. While repairs allowed for gradual resumption of services on Wednesday, significant delays and cancellations persisted, impacting New Year's Eve plans. Operator Getlink stated the issue was technical, with no suspicion of foul play, and aimed for a return to normal operations overnight.
