On 16 February 2015, Canal+ and Sky Atlantic announced that a second series would begin production in March, set to air in early 2016, entitled "The Tunnel: Sabotage", and consisting of eight episodes. Series 2 would focus on the crash of an airliner into the English Channel, with Dillane and Poésy returning; it premiered on Canal+ on 7 March 2016. The debut on Sky Atlantic was originally set for 5 April 2016 but was put off until a week later in deference to the Brussels terrorist attacks on 22 March 2016. It premiered in the UK on 12 April 2016 and was made available via Sky's On Demand service.
