-
- The TGV-PSE apparently needs about 3.5 km (2.2 miles) for an emergency
- stop from 270 km/h (168 mph). This implies to a deceleration rate of
- about 1/12 gravity. I say "apparently" because my source appears to
- show the same emergency stopping distance from 235 km/h, so something
- must be slightly wrong there.
-
- In any case it would be close to that distance. The TGV uses 6-aspect
- (cab-)signaling, with signal blocks 2.1 km (1.3 miles) long...
