Eurostar has announced a year-round service to Geneva via Lille from 14 December 2014.
The route from London St. Pancras is in partnership with TGV Lyria, meaning passengers will be able to purchase through-tickets from London to the Swiss city but will transfer onto a TGV Lyria train at Lille.
The four-times weekly route, which starts on 14 December, will operate on Mondays, Thursdays, Saturdays and Sundays. Tickets are available for booking from 9 October.
The outbound London to Geneva service will take six hours and 18 minutes with a 37-minute connection in Lille.
Lille Europe railway station is being refurbished to increase capacity at the Eurostar terminal. The upgrade will be unveiled in December, coinciding with the launch of the new Geneva service.
