Railroad ties in the US are nearly all made from oak that has been treated with a preservative. For higher speed track and where continuous welded rail (CWR) has been installed, concrete ties are in use for many lines rather than wood. Metal ties have been tried, but in the past were considered somewhat unsuccessfule. An exotic wood called azobe has been used, and it seems to be preferred over treated oak where it has been used. Composite ties have also been used.
