5.2.6.  Coordinate with the Secretary of the Army, or designee, for the following DoD Component installation transportation engineering matters:  DoD installation and activity transportation engineering issues and the need for transportation engineering consultation services.  Requirements for new and improved transportation engineering features in defense transportation processes, equipment, and facilities.  Planning, design, and development of major new defense installation and activity modal facilities and need for impact evaluation.

5.2.7.  Incorporate efficient and effective use of intermodal transportation techniques and containerization in the design and construction of new or modified installation and activity transportation equipment and facilities.

5.3.  The Combatant Commander, USTRANSCOM, shall:

5.3.1.  Identify DoD transportation engineering interests in civil transportation programs and ensure coordination.

5.3.2.  Represent the Department of Defense in negotiations and discussions with civil transportation agencies and industry concerning common-user transportation engineering matters.

5.3.3.  Identify DoD Component-coordinated transportation engineering interests in common-user DoD transportation systems construction and modification programs.

5.3.4.  Determine DoD common-user engineering and infrastructure criteria to:  Manage the DoD Highways for National Defense Program.  Identify STRAHNET and required connector highways and coordinate with Federal and State transportation authorities.  Establish and coordinate effective design standards and criteria for safe movement of DoD equipment on civil highways.  Review and analyze DoD access road needs and, when appropriate, those of other Federal Agencies, and certify to the Secretary of Transportation, on behalf of the Secretary of Defense, the civil highway needs of the Department of Defense in accordance with reference (c).  Ensure repair of damages to public roads serving DoD ballistic missile sites under conditions of DoD Instruction 6055.4 (reference (d)).  Advise and assist the DoD Components with their resource programming to meet defense access road needs.  Manage the Railroads for National Defense Program to identify, review, and analyze DoD interests in civil rail lines that include, but are not limited to:  The STRACNET and civil rail lines important to national defense.  The joint list of DoD installations and activities requiring civil rail lines to accomplish their assigned missions.  Rail criteria for oversize/overweight defense shipments.  Readiness criteria for maintenance of civil rail lines.  Impact assessments of railroad abandonments, bankruptcies, and mergers on national defense interests.  Assist and advise the DoD Components regarding their financial assistance to protect essential civil sector rail line(s).  Solicit civil sector support and consideration of DoD needs for civil rail lines and integration into policy, plans, standards, programs, and regulations of the railroad industry.  Manage and conduct transportation engineering programs for analyses of common-user defense-important seaports.  Monitor modal legislative processes to ensure that DoD transportation engineering interests are protected.  Ensure that the DoD Component-coordinated transportation engineering interests are considered in defense common-user transport construction and modification programs.  Publish multi-Service regulations for the Highways and Railroads for National Defense Programs.

5.4.  The Secretary of the Army shall:

5.4.1.  Ensure the use of effective and safe transportation engineering techniques into DoD installation transportation processes, equipment, and facilities by providing appropriate consultation.

5.4.2.  Promote incorporation of appropriate Federal standards into the design and construction of DoD Component highway facilities, as directed by reference (d).

5.4.3.  Promote efficient and effective use by the DoD Components of intermodal transportation techniques and containerization.

E1.1.1.  Civil Transportation Agencies.  A term used collectively for those organizations that have statutory responsibilities to incorporate DoD requirements into non-DoD, Federal, State, or local transportation programs and regulations involved with highways, railways, ports, and intermodal systems; e.g., the U.S. Department of Transportation, the Federal Highway Administration, the Federal Railroad Administration, the U.S. Maritime Administration, and State and local transportation departments.

E1.1.2.  Defense Transportation System.  That portion of the global transportation infrastructure that supports DoD common-user transportation needs across the range of military operations.  It consists of those common-user military and commercial assets, services, and systems organic to, contracted for, or controlled by the Department of Defense.  Also called the "DTS."
