As I said several times, third rail cannot be allowed to enter a car again. That will be the mantra. Cars will be more puncture resistant as a result.I don't understand your logic about braking. A higher braking rate means a shorter braking time and hence distance. Stopping from 60 mph at 3.0 mphps takes 20 seconds, at 5.0 mphps it takes 12 seconds. Braking distance is about 350 feet less at the higher rate, maybe just enough to prevent this accident. LRV: 65 mph, 6.15 mphps. This at least shows that much higher brake rates are possible on rail vehicles. Maybe hydraulic brakes are next for MUs? |
