I'm watching this video by Rory Suterland in which he claims at 6:15 that Eurostar could have implemented a WiFi network for £600, but instead choose to spend £6,000,000 decreasing the journey time by 40 minutes.
Is this a substianted claim? This seems to be an awfully low amount to implement a working and usable Wi-Fi network for a tunnel spanning from London to Paris and then to Brussels that will work inside a train travelling through.
