Methods for Running Express/Local Trains on Existing Lines of Urban Rail Transit
Current solutions for enhancing the efficiency of existing urban rail transit lines are limited.As a pioneering initiative,the concept of running express/local trains on these lines presents a versatile solution for Shigh-quality development scenarios.After systematically reviewing the methods for running express/local trains on existing lines,this paper introduces four distinct strategies tailored to the unique features and operational needs of different lines:employing extended intervals for rapid trains,implementing alternate station-skipping for accelerated service,utilizing malfunctioned train stop lines for express/local runs,and operating partial-route shuttles for express/local trains.Drawing from domestic and international case studies,this research delves into the operating principles,advantages,disadvantages,and operational requirements of the aforementioned methods.Additionally,the necessary modifications for implementing express/local train services on existing lines are discussed.
