for Facilities Engineering, Design and Construction.
Theft and Vandalism. Protective measures shall be carefully
13.2.2
considered in the design of yards.
Efficiency. Yards shall be designed for efficient switching and
13.2.3
handling tasks and to minimize delays and demurrage charges.
Expansion. Yard layouts shall provide for anticipated future
13.2.4
expansion so that the number and length of tracks in them may be increased as
required with minimum interference to operation or minimum relocation of
existing trackage.
Track Capacity. In computing track capacity in terms of number of
13.2.5
cars, a minimum of 50 feet per car shall be used for all tracks other than
those to be used for special equipment.

HDBK-1005/3, Drainage Systems.
Communications. Facilities such as teletype, pneumatic tube
13.2.8
systems, loud speakers, talkback, paging systems, television, telephones, and
radios shall be considered to expedite operations. See NAVFAC MIL-HDBK-
1004/7, Wire Communications and Signal Systems.
Track Arrangements. Main tracks should not pass through a yard,
13.3
but should be connected to yard tracks as directly as practicable. Crossovers
to facilitate all normal and regular movement in the yard, with minimum
interference between the different movements, shall be provided.
Body Tracks. A series of parallel tracks which could be part of a
13.3.1
storage, repair, receiving, classification, or departure yard shall have a
minimum of 14 feet between centers. Where a body track parallels a main or
important running track, a minimum of 20 feet between centers shall be
provided, subject to state regulations on clearances. See AREA Manual,
Chapter 28, Part 3, Section 3.6, Legal Clearance Requirements by States.
