Abstract Metro systems are often faced with reliability issues; specifically pertaining to safety, accessibility, train punctuality, and stopping accuracy. The project goal was to assess the reliability of the London Underground’s Jubilee Line and the systems implemented during the Jubilee Line extension. The team achieved this by interviewing train drivers and Transport for London employees, surveying passengers, validating the stopping accuracy of the trains, measuring dwell times, observing accessibility and passenger behavior on platforms with Platform Edge Doors, and overall train performance patterns. ii Acknowledgements We would currently like to thank everyone who helped us complete this project. Specifically we would like to thank our sponsor Malcolm Dobell for his encouragement, expert advice, and enthusiasm throughout the course of the project. We would also like to thank our contacts at CPC Project Services, Gareth Davies and Mehmet Narin, for their constant support, advice, and resources provided during the project. We would also like to thank the staff, who gave us permission to conduct our measurements of stopping accuracy, and drivers, who took time out of their day for our interviews. Specifically, we would like to thank: Joshua Rosenstock, our advisor Adrienne Hall-Phillips, our co-advisor Sarah Crowne, our ID 2050 professor Malcolm Dobell, non-executive director at CPC Project Services Gareth Davies, systems engineer at CPC Project Services Mehmet Narin, systems engineer at CPC Project Services James Goff and Charlotte Hughes, project managers at CPC Project Services Fernando Soler, service control manager on the Jubilee Line, for providing valuable information on the Jubilee Line and access to the Jubilee Line Control Center Phil O’Hare, general manager on the Jubilee Line, for taking time out of his schedule to talk with us about the Jubilee Line Steve Walling and Eric Wright, former and current sponsors for London projects with TfL iii Authorship Throughout the completion of the project, the responsibilities were shared equally between the four group members. Each section of the paper was iteratively written and edited by each group member. Individual group members were in charge of sections of the paper, but fellow group members helped to edit and contribute to the sections. Every diagram created was collaboratively designed before one group member completed the final design steps. We believe the collaborative nature of our group contributed to the success of this project. iv Table of Contents Abstract ........................................................................................................................................... ii Acknowledgements ........................................................................................................................ iii Authorship...................................................................................................................................... iv Table of Contents ............................................................................................................................ v Table of Figures ........................................................................................................................... viii Executive Summary ........................................................................................................................ 1 1 Introduction ................................................................................................................................ 11 2 Background ................................................................................................................................ 14 2.1 Rail Transportation .............................................................................................................. 14 2.1.1 Transportation Overview .............................................................................................. 14 2.1.2 Modernization of Railway Transportation ................................................................... 15 2.2.
