"Our journey home is still too long. If we drive, it will take more than six hours. Even if the expressway is built, it will take about four and a half hours. If a high-speed railway can be built, it will take about three hours. The gap is still very obvious." Aiden Tang looked at the scenery whizzing by on both sides and couldn't help but sigh!
"There are not many high-speed trains in our country now. When I traveled with my father before, we basically took green trains. As far as I can remember, I have never taken a high-speed train." Olivia Su said as she recalled.
"There should be only two. And the designed speed should not exceed 200 kilometers per hour. This speed is still too slow. If the speed of the train can be increased to 350 kilometers, it can barely be called a high-speed railway." Aiden Tang responded.
"Our country's economy is developing rapidly, and more high-speed railways will be built soon. It won't be long before it will be much more convenient for us to go home," Olivia Su said with a smile.
"Before the technology and cost are lowered, large-scale development is probably impossible. Don't worry, solve things one by one. Sooner or later, our country's high-speed rail will connect every corner." Aiden Tang seemed confident.
