Most railroad companies will request a review and approval of the Sealed(100%) plans (often referred to as an Exhibit B on construction projects) to verify certain elements of the design have not changed from the Exhibit A. Railroad company approval of the Sealed(100%) plans may be/is required for underpass and overpass projects.

Do not include the Exhibit A in the Sealed(100%) plans unless there is information which is not contained in the rest of the plans such as track realignments.
