This report documents the results of a survey of entrainment technology conducted for the VLCR project. The technology review was conducted to evaluate the state-of-the-art in train formation and to identify those areas requiring special attention for Automated Guideway Transit (AGT) systems. The information which is summarized herein was derived through: (1) a literature search and review; (2) discussions with coupler manufacturers; (3) a questionnaire to rapid transit operators; and (4) a study of transit authority coupler specifications. The methods and the results obtained within each of these activities are described within the report. The literature search involved both manual and computerized search techniques. The most applicable documents are listed in the Appendix: "Annotated Bibliography". The discussions with coupler manufacturers allowed the formation of a list of existing coupling equipment applicable to systems and the assessment of potential difficulties in the adaptation of coupling equipment to AGT vehicles. Areas probably requiring significant further development were also identified. A questionnaire dealing with automatic coupling equipment and techniques was then prepared and transmitted to seven transit system operators. Through automatic entrainment and extrainment (or train separation) of individual vehicles, it is hoped that the operational efficiency of AGT systems may be improved. The report concludes, in part, that due to the lack of information in the area of automatic vehicle longitudinal control, the formulation of appropriate concepts in this area will require more original and basic work. The report presents a number of preliminary conclusions.
