Eurostar has maintained a monopoly on Channel Tunnel rail services for nearly 30 years, but recent regulatory changes and rising demand for lower-carbon travel options have attracted competitors. A report from the Office of Road and Rail has mandated Eurostar to allow access to new operators at Temple Mills depot, potentially leading to increased competition and lower prices for passengers. Companies like Virgin Group, Evolyn, and Gemini Trains are expressing interest in launching services by 2029. The report suggests that capacity issues at Temple Mills may not be as significant as Eurostar claims, paving the way for new entrants in the market.
