Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate has he made of average wi-fi speeds on (a) Thameslink, Southern and Great Northern, (b) Southeastern and (c) Chiltern trains in (i) 2017 and (ii) 2018 and (iii) 2019.

The Department has not undertaken an assessment of the average Wi-fi speeds on these routes. Ofcom are currently surveying the mobile signal strength to the train across the rail network. We expect the first publication to be later this year.
