2-24. PREPARATION FOR MOVEMENT (continued).
d. Air Movement.
The CBT and CBT components in all configurations are certified by the Air Force for transport on C-5 and C-
17 aircraft. The following configurations are certified for air transport by the Air Force:
CBT: C-141 and C-130 in reduced configuration, 102 inches.
IBC and Bridge Erection Boat: C-130 and C-141 as palletized loads.
e. Rail Movement.
(1)
U.S. Rail. Transportation of the CBT by rail, in the United States, is based on the use of the "worst
case" 50-inch (127 cm) flatcar. The deck height of this flatcar is 50 inches (127 cm) above the top of
the rails. Based on the American Association of Railroads Outline Diagram, the M1977 CBT can be
transported by rail, providing the height and width reduction procedures are completed. The M1977
CBT with the M15 BAP cannot be reduced in dimensions and therefore exceeds the height and width
requirements of rail transportation.
(2)
Foreign Rail. Transportation of the CBT by rail is based on the use of the RES-type or REMMS-type
flatcar. The deck height of these flatcars is 48.7 inches (123.7 cm) and 49.6 inches (126 cm), respec-
tively. Based on the Gabarit International de Chargement (GIC) equipment gage, the M1977 CBT can be
trans-ported by rail, providing the height and width reduction procedures are completed and the air
cleaner is removed. The M1977 chassis with the LHS and the BAP cannot be reduced in dimensions
and therefore is not cleared for unrestricted rail transport. However, it may be possible to transport in
this configuration based on the planned rail route. The planned rail routes need to be checked for
clearances for this configuration.
