Recommendation 27

Connectivity along major rail routes remains poor. Passengers can struggle to make calls, stream videos or work online. The Department told us that improving connectivity on railways is challenging. It explained that it is hard for the signal to penetrate through tunnels, deep cuttings and safety glass on modern trains. According to the Department, improving coverage on trains would be expensive and require complex infrastructure along the side of the track, which, it described, as more difficult than improving coverage on roads. The Department further explained that there is a weak commercial case for individual mobile network operators to invest in railway coverage, due to the high costs for infrastructure and marginal commercial benefits.53
