Key features of system include the following: • General – Ability to manage, share, and manipulate data representing a railroad's physical plant; train schedules, traffic volumes, and train consists; railroad operating schedules; traffic control; alternative analysis scenarios.

... 69 methods so that it will generate acceptable outcomes in a wider range of operational situations than currently available. The three proposed improvements that would make SU more applicable to many challenging operational situations where it currently has limited usefulness are as follows: • Automated repeated simulations; • Find best dispatching from multiple sketch runs, then apply to full simulation; and • Apply a priori heuristics.
