For some time, I understand, they've been making railroad cross-ties out of
concrete.

Evidently some believe that concrete will last longer than
creosote-impregnated wood...

Some special attribute of this concrete to prevent it cracking from
vibration?

In Japan they use a rubber pad between the rail plate and the concrete.
