semiannual inspections are taken care of by the TRS. Units of the
MATCOM make the annual inspection of motive power; however, the TRS
makes the annual inspection if there is no MATCOM in the theater.
(2) Maintenance of rolling stock. Organizational and direct
support maintenance are responsibilities of the TRS. Organizational
maintenance is performed by operating units and by car inspectors at
the train's originating point and at en route inspection points to
insure safe movement. Airbrakes, running gear, and other parts are
inspected; journal boxes are examined and lubricated. For ambulance
trains and cars, the ambulance train maintenance sections and crews
take care of those items just mentioned; in addition, their
responsibilities include stocking of other than medical supplies
fuel, water, ice, etc.; placing cars on and removing cars from pre
cooling or heating facilities; and operating and controlling heating,
airconditioning, and carlighting equipment. Direct support
maintenance is done by the railway equipment maintenance company and
the mobile workshop. Such maintenance consists of providing safe
operation of freight equipment and comfortable operation of passenger
and hospital cars. General support (GS) maintenance is taken care of
by the dieselelectric locomotive repair company and by the car
repair company of the materiel command. Not only does this GS
maintenance activity support the maintenance overflow from direct
support but also takes care of the heavy maintenance involved in
stripping, assembling, erecting, and painting railway cars and in
assembling and inspecting knockeddown new equipment brought into the
theater.
(3) Maintenance of special and captured equipment. The TRS is
responsible for maintaining such special equipment as that used on
wreck trains as well as wreck and other cranes, heavy roadway
equipment, tools add enginehouse machinery, and other similar
equipment. Captured railway equipment that may have been taken over
for operation is repaired and serviced by the TRS before being sent
out on the line.
