2.4. MEDICAL COMMAND
The medical command owns and operates ambulance trains to
evacuate patients from hospitals or holding units of the combat zone
to the COMMZ, between hospitals of the COMMZ, and from hospitals to
aerial or water ports of embarkation. The train commander is a
Medical Corps officer; he is responsible for the command,
administration, coordination, and operation of the ambulance train
unit. The TRS, however, furnishes the motive power and is
responsible for scheduling, operating, and maintaining the train.
Running repairs and direct support maintenance are provided by TRS
ambulance train maintenance units which are attached to the senior
transportation railway unit in the theater.
2.5. ENGINEER COMMAND
The engineer command (ENCOM) constructs, rehabilitates, and
performs major maintenance on military rail lines and rail
facilities, including structures, bridges, tunnels, and roadbeds.
The ENCOM stocks construction equipment and materials, such as rails,
spikes, ties, and ballast, as planned for and requested by the TRS.
The ENCOM is also responsible for constructing and rehabilitating
primary electric power sources, thirdrail or overhead systems, and
lines needed to transmit electric current from these sources for
operating electrified railways and railway signaling systems. The
overall view of how the ENCOM fits into the maintenance and supply
picture is discussed in paragraph 2.7.
The transportation railway service is responsible for planning
and recommending to the transportation command (TRANSCOM) the rail
facilities that must be constructed or rehabilitated. The plans are
coordinated with the engineer command and, when necessary, the TRS
furnishes technical advice and assistance and cooperates closely with
engineer units. When directed, the railway service aids engineer
units to accomplish their tasks.
The TRS rehabilitates within its capabilities, but when major
repairsmaintenance requiring major items of construction
equipmentmust be made, it requests the engineer command to make the
repairs and do any necessary construction. Such requests are
forwarded through command channels to the transportation command for
coordination with the engineer command and for establishment of the
