Compared with expressways and traditional double-track railways, high-speed railways are more efficient and can meet the needs of large-scale long-distance transportation. As far as transportation efficiency is concerned, the operation time, construction cost and line capacity of high-speed railway are 2 ~ 3 times that of expressway and traditional double-track railway.
