Perhaps you should ask Network Rail, who spent ten years and 9bn failing to do this within living memory. Oh. Are there any sections that are 140mph ready? No and there is no point on a mixed-traffic railway. There won't be much 140mph running if the train in front is only doing 60mph. There could be with the right signalling if the 140MPH train is regularly stopping and the 60MPH train is a through freight train. A 140mph train will be an express, not regularly stopping. Stoppers need to have higher acceleration, but rarely have or need a top speed of more than 110mph. Another problem with mixed traffic lines is that heavy freight trains usually lose speed when climbing; modern EMUs do not. So the speed discrepancy becomes even wider on gradients. |
