The graphical portrayal of train operations using time-distance diagrams has long been used to develop schedules and for other analyses. The availability, however, of relatively simple, practical, user-friendly computerized tools to do the related calculations and plots is limited. The development and application of a package of PC-driven programs that accurately simulates train operations, plots bidirectional operations charts and schedules, and allows sensitivity testing of various operating parameters are discussed. The package was tested using data derived from the operations of Philadelphia's Market-Frankford subway elevated rail rapid transit line. It then successfully generated graphical schedule (string-chart) diagrams for this two-track line under a series of operating assumptions. Of special interest was the testing of the present schedule while a section of track 599 m (1,964 ft) long between two stations was taken out of service. Such a package can be easily developed and used for a variety of sensitivity analyses, graphical scheduling, and other operational tests.
