Does {tIH} mean one rail, or one track (i.e., a pair of rails)?

There may be other configurations, but most railroad tracks at the current time on Earth have two parallel rails. It seems that {tIH} should be the word for one such rail, and that a track is therefore always {tIHmey}. This is similar to how we have a word for "hotel", but it's just a collection of "guest rooms" {mebpa'mey} in Klingon. But I wanted to make sure.
