The reality of train travel is that trains go places where mobile networks are at their weakest. Rural areas with low population densities don’t encourage mobile operators to build out expensive 4G and 5G networks meaning there is often little or no connectivity from train to the Internet on parts of a passenger’s journey.

This provides a challenge to train-based Wi-Fi services particularly as web traffic is increasingly dominated by video streaming services. Caching this content on a local server has typically been the approach taken, but this has focussed more on niche, regional content suppliers which struggle to meet the expectations of passengers accustomed to high quality services provided by Netflix, Amazon and BBC iPlayer.
