Re: Beeching's revenge
A quick check indicates the video either doesn’t cover the entire stopping time or the stopping distance is misstated.
Whilst TGV clearly comes to a halt after 38s of video, a quick calculation shows that a train travelling at 320 kmh would cover 3378m in 38s.
Counting gantries (26) and assuming typical distance between is 50(*), gives a total distance of circa 1300m in 38s.
(*) typical spacing of overhead line gantries for 140mph(225kmh) in the UK are 64~73m. Eurostar (300kmh) it’s circa 50m.
Some additional searching provides a calculated stopping time of under 90s, based on a number of assumptions, which seem more reasonable.(in the event of total power failure it might be slightly faster).
This thus gives a distance covered of 8000m (5 miles) at 320kmh. Thus that 2.5 miles forward visibility is an understatement..
