This manual provides guidance for design and rehabilitation of railroad track, terminals, and loading facilities, along with some information on construction. The guidance in this manual is primarily for railroad lines operated at lower speeds and with lower traffic volumes than those most commonly found in the commercial industry. The guidance on terminal design is for small terminals handling military cargo: primarily tracked or wheeled vehicles and intermodal containers. This manual, supplemented with the specified references, should provide sufficient information for general purposes. Most projects, however, include some aspects that are very site-specific or some conditions that are not common. Designers are encouraged to obtain assistance when unusual or unfamiliar situations are encountered.
