Apparently, my English isn’t so good. For instance, when I read this article, I had no idea that GNER was a UK-based rail transportation entity. Even worse: when I saw the word "chuffed" in the article, all I could think of is how to describe a chimney sweep that fell down the shaft. "Did you hear about poor old Charlie? He leaned in too far and got chuffed!"
Anyway, chuffed must mean "really excited" since GNER is providing free WiFi on a trial basis for their summer riders. Passengers simply enable WiFi on their mobile device, open a browser and GNER will do the rest. Each train is equipped with both a satellite dish and cellular antenna for 3G and GPRS connectivity, which is then routed as needed to the passengers throughout the train. Wow, if I had this kind of rig on my vehicle, I suppose I’d be chuffed too.
