Substitution of parties pursuant to Rule 25 does not affect the right to use depositions previously taken; and, when an action in any court of the United States or of any state has been dismissed and another action involving the same subject matter is afterward brought between the same parties or their representatives or successors in interest, all depositions lawfully taken in the former action and duly prepared, certified, and delivered in accordance with Rule 30 may be used in the latter as if originally taken therefor.
