(1) A new high-speed passenger dedicated railway adopts a common operation mode of high-speed and medium-speed trains. And Vmax is 350km/h, V, is 250km/h. When the curve radius is 6000m, please solve the following problems. 1 If the speed coefficient is 0.80, how much the outer rail superelevation should be laid in order to ensure uniform wear of inner and outer rails? 2 What is the corresponding Aha or Ahs when the high-speed train and the medium speed train pass through the curve? 3 If we want to ensure Aha<70mm and Ah,<50mm, what is the range of the superelevation of the curve?
