GENERAL
INSTRUCTIONS
Loading rules 4, 5, 7, 11, 15(g), 19, 19A, 19B, and 19C appearing in section 1 of the Rules Governing the Loading of
Commodities on Open-Top Cars, published by the Association of American Railroads, provide applicable guidelines and
are mandatory in application.
Section Ill. TRANSPORT OF FOREIGN RAILWAYS
7-8. General
The transportability guidance contained in this
section is applicable when the HEMTTs are trans-
ported on foreign railways. Consideration is given
to single and multiple vehicle movements for the
types of flatcars normally used for the movement
of this type of vehicle. When loaded on a suitable
flatcar, the HEMTT can be transported, with some
restrictions, within European countries with the
Gabarit International de Chargement (GIC) (for-
merly PPI) gauge railways; this also applies to the
majority of the countries in the Middle East,
South America, Australia, India, and Pakistan. In
the Middle East and South America, the clear-
ances vary by country, and each country will re-
quire a separate check. In Australia, India, and
Pakistan, wide or broad railways provide greater
clearance and fewer restrictions. Because of the
various systems and clearances used by different
countries, evaluation of transport capability must
be made on an individual basis.
7-9. Transport on Foreign-Service Flatcars
The HEMTTs can be transported on many foreign-
service flatcars. To comply with the dimensional
requirements of the GIC clearance diagrams, the
HEMTTs must be reduced to their minimum ship-
ping configuration. At the reduced configuration,
the HEMTTs can be moved, without restrictions,
on standard flatcars throughout Europe. The ma-
terials required for blocking and tiedown of the ve-
hicles on foreign-service flatcars are essentially
the same as those used for rail within CONUS. De-
tailed guidance is contained in the 4th Transporta-
tion Command Pamphlet 55-2, Tiedown Guide of
Rail Movement, and may be obtained from the 4th
Transportation Command, Oberursel, Germany.
