Question to the Department for Transport:

To ask Her Majesty’s Government what steps they are taking to improve the wireless internet signal on the train network, in particular between London and Sheffield.

Availability of mobile broadband services on trains can be an issue, partly due to physical barriers to radio signals reaching the railway track, include railway cuttings and tunnels and due to signal weakening, called attenuation, caused by train carriage walls and windows.

In June 2015, the Government launched a Call for Evidence to support delivery of improved coverage, with the intention to build on the work that has already happened across industry. On-train Wi-Fi addresses some of the issues, however we recognise that there is more to do that will require enhancements to trackside infrastructure. That’s why we are working with the rail and telecommunications industries to reach a shared understanding of the technical and commercial challenges, and seek out potential solutions for the rail network, including the London to Sheffield line.
