DOT Numbers

On construction or railroad capital improvement projects that introduce new crossings (at-grade or grade separated), the railroad company or industry must obtain a new DOT number for the crossing. The DOT number is assigned by the railroad company but may be issued by RRD
in some cases.

Projects which will require new DOT numbers assigned for existing crossings include:

Converting an at-grade crossing to a grade separated crossing or vice versa.

Converting an underpass to overpass or vice versa.

Relocating an at-grade crossing.
