Why do I need a maglev to go 70? A bus can go 70. Any old steel-wheeled train can hit 200.

- melling 10y agoHow long does it take an "old steel-wheeled" train to get to 200 mph? How long does it take it to stop? Why don't you look at a train schedule in the US and tell me how many trains go 200 mph. Hint: zero! Most trains average less than 50 mph. As for a bus, you aren't going to drive it at 70 through the streets of LA or Manhattan. In fact, it's probably going to be tough getting it to 60 in this traffic: http://www.mercurynews.com/wp-content/uploads/2016/10/sjm-confestion-1004-03.jpg?w=928 http://www.mercurynews.com/wp-content/uploads/2016/10/sjm-co... A maglev carries 200-300 people? Your average bus holds 50?
- honkhonkpants 10y agoElectric, steel-wheeled trains are already limited by passenger comfort in acceleration and deceleration. Making a trainset that accelerates and decelerates more quickly is a non-problem that nobody wants to solve.
- melling 10y agoOk. Why is China building low-speed maglevs in Beijing and not using buses and high-speed rail? They have over 10,000 miles of hsr?
- honkhonkpants 10y agoBeats me. There are reasons to build low-speed maglevs on sites where wheeled trains don't work well. For example a maglev can climb steeper grades, and you can run them right through dense urban areas where noise might be an issue.
