Back in the dark days of TES Opinion... [or the bright shiny days when we were allowed a place to have an Opinion! - take your pick]... I posted a thread wondering if HS2 was going to be redundant before it even got started because of Elon Musk and the Hyperloop. Well the Hyperloop is getting closer... http://www.ibtimes.co.uk/elon-musk-build-hyperloop-bullet-train-within-weeks-1525529 So the test track is going ahead. Now of course, the test track could be a resounding failure, who knows. Still, it interests me.
