This report presents the Initial Interface Standards for subsystem components of a typical rapid transit car system. These standards were derived from an interface definition analysis of 128 product-applications on seven of the newest North American rapid transit car system designs. Twenty one major components of a rapid transit car which the carbuilder purchases as shippable items were selected for interface definition. Analysis of the product-specific data which was made available by the original equipment manufacturers provided the basis for either defining the functional and physical interfaces of each major component and the minimal space which must be allocated upon the carbody structure or truck frames to incorporate a major component into the carbody structural design, or determining that a major component does not appear to be amenable to interface standardization. Transit industry adoption of interface standards for car-mounted equipment should result in cars which would cost less to build and own.
