Chapter 2
THE TRS AND ITS RELATIONSHIP
WITH OTHER AGENCIES
2.1. GENERAL
The transportation railway service consists of the command and
supervisory, operating, maintenance, and service units needed to
operate railway trains, maintain rail lines of communications, and
perform organizational and direct support maintenance of locomotives
and rolling stock in a theater of operations. Normally, the TRS is
an interzonal service and may operate over long distances throughout
the theater.
To insure that the capabilities of the TRS are
exploited to the fullest extent possible, all supervisory and
subordinate rail units in a theater are assigned to and operate under
the command and supervision of a senior transportation organization,
normally the transportation command of the theater army support
command (TASCOM). Regardless of the extension of the railway service
through
other
commands
or
territorial
jurisdictions
in
the
communications or combat zones, commanders of area support commands
or areas within the combat zone influence rail operations only by
coordination through command and technical channels.
The senior railway unit in a theater is responsible for planning
the organization of the railway service and the employment of all TRS
units. In a theater, the senior railway unit may be a transportation
railway group.
Where there are three or more groups, a railway
brigade is the senior railway unit; where there are fewer than three
groups, they are under TASCOM's transportation command.
A railway
group can command from two to six railway battalions and normally
supervises up to 960 kilometers of main rail line.
Each battalion
commands attached operating and maintenance units and normally
controls the operation of 145 to 241 kilometers of rail line--a rail
division.
Rail engineering, equipment maintenance, and train
operating companies, as required, are attached to the battalion.
