Description

New IEEE Standard – Active. The general parameters used in the design of direct current overhead contact systems used in transit systems are defined in this guide. The guidelines mentioned in this document are intended to be used for the design of either new or expanding transit systems where a legacy of design standards does not exist. These guidelines are not intended to replace or supersede existing design standards, but to formalize the design process
