Crossing Identification Numbering System

Every at-grade or grade separated crossing is assigned a unique U.S. Department of Transportation (USDOT) identification number, also referred to as a DOT number, consisting of six numeric characters and an alphabetic character. This applies to all public and private
road and pathway
crossings.
For
at-grade crossing locations, the DOT number is typically seen on the Emergency Notification Sign (ENS) at the crossing or on a sign found on the railroad cabin.
If needed, new crossing DOT numbers shall be obtained from the railroad that operates over the crossing. If a new crossing is proposed, RRD will request a new DOT number from the affected railroad. The new crossing number will be populated into the TRIMS database.
