Why per­sist with Wifi?

Is WiFi still rel­e­vant for new trains? ( RAIL 865)

I travel reg­u­larly be­tween In­ver­ness and Glas­gow and Lon­don on the Cale­do­nian Sleeper (even with its old rolling stock, this is an in­cred­i­ble ser­vice, by the way).

Ex­cept in some of the depths of the High­lands, there is 3G and 4G cov­er­age on my mo­bile net­work (Voda­fone) al­most through­out the jour­ney, one of the long­est on the whole rail net­work. And it’s good enough to watch en­tire pro­grammes on BBC iPlayer with­out any breaking-up of pic­tures or sound.

And as data on mo­bile gets cheaper, and quan­ti­ties larger, is WiFi in­vest­ment worth it, par­tic­u­larly as pub­lic WiFi net­works of­ten re­quire ef­fec­tive lo­cal man­age­ment in­ter­ven­tion to stay on­line? There are also pub­lic se­cu­rity and legacy tech­nol­ogy is­sues. Fred Sil­ver, Stornoway
