One key obstacle, access to a train maintenance and storage facility, looks to have been overcome following a decision by the Office of Rail and Road (ORR).
The regulator said Eurostar’s London depot would be able “if required” to accommodate additional trains, following receipt of an independent report it commissioned.
The report follows growing interest in providing extra services between St Pancras and continental Europe, with Virgin Trains, Spanish start-up Evolyn and a UK brand, Gemini Trains, keen to enter the market.
