“I wonder how fast this train is going. Surely it should be easy to find out, as my phone does gps magic” and other stupid and deeply ignorant things I have thought recently.

My iphone doesn’t offer a native speedometer, and the ios app store is absolutely choked with offerings which will spew ads and harvest a load of data about me and “offer in-app purchases”. All this for something my phone hardware can do already!

Anyway, in conclusion, I still hate modern technology.

Anyway, I’m pretty certain it is going really fast, which is always nice.
Blink and you’ll miss it, but every 20 minutes or so the advertising screens on the ceiling of the carriage do in fact say how fast you’re going.
