China has the largest network of high-speed trains in the
world. It stretches a whopping 15,500 miles all over the
country. But while that all sounds impressive, I can't help
but wonder why they'd spend a fortune on building such a
vast bullet train network when airplanes exist?

First, most central train stations are downtown, so you
can easily reach them by subway. You don't need to go
through extensive pre-boarding security. And even if
there are some delays, they don't happen too often and
are much shorter than those at airports. Also, with their
wider seats, more legroom, and freedom to move around,
modern bullet trains offer their passengers more comfort.
That's only the beginning of the list of reasons why
high-speed trains rock.
