The HeathrowExpress rail service offers train journeys to Heathrow airport, but the British rail network is not as integrated nor as fast as its continental brethren.
Customers on HeathrowExpress can use a Wi-Fi HotSpot service with a broadband connection of 2 Mbps throughout their entire journey -- even through a six-kilometer tunnel, helping travelers check their emails, view flight information or keep up-to-date with the latest news.
