(5) Design the track, roadway, and terminal and support facilities. From the traffic and wheel load
estimates and the characteristics of the selected route, determine track, roadway, and drainage
requirements.
c. Rehabilitation. For rehabilitating existing lines and facilities, chapters 5 through 8 are required, along
with portions of chapter 2.
5. SUPPLEMENTARY MATERIAL. Listed below are references and other material generally required for
railroad design and rehabilitation. Full citation of references is given in appendix A:
a. AREMA Manual for Railway Engineering and Portfolio of Trackwork Plans.
b. Installation Transportation System Capability Study.
c. Drainage design guides.
d. Railroad Track Standards (TM 5-628/AFR 91-44).
e. Detailed maps (including contour maps) of the area through which the railroad will run.
6. USING THE AREMA MANUAL FOR RAILWAY ENGINEERING.
a. The American Railway Engineering and Maintenance-of-Way Association's Manual for Railway
Engineering is a standard industry reference and is cited throughout this technical manual. It contains a
wide range of guidance to cover a variety of needs, with emphasis on commercial lines carrying
substantial freight traffic. As a broad range of specifications is often given, proper use of the AREMA
manual requires that the designer select the particular specifications that are most appropriate for a
particular project.
b. The AREMA manual is written primarily for the commercial carriers, that have their own company
policies and procedures. The material was prepared with the assumption that many details need not be
covered, as a company's own practices would govern. Therefore, it is usually necessary for military
designers to provide details above and beyond the material contained in the AREMA manual. In addition,
requirements for operation on military railroads may sometimes differ from those commonly found on
commercial carriers. In these cases, the design guidance in this technical manual may vary from that
found in the AREMA manual.
c. For these reasons, when preparing designs and specifications, the use of general statements such
as "meeting AREMA specifications" should be avoided. Such statements often leave the choice of
materials or procedures wide open and can lead to an undesirable or unsatisfactory product. Designers
should clearly specify the work to be done and the acceptable materials for use in construction.
7. APPLICABILITY OF STATE AND COMMERCIAL RAILROAD STANDARDS.
a. States often have standards, particularly for clearances, which should be met during new
construction or rehabilitation. These standards may be obtained from the appropriate State departments
of transportation and public utilities.
