train_dynamics

This is a set of parameters associated with a specific train. These parameters are sufficient that a process can determine the arrival time of a train at an HRI and determine how long the HRI will be occupied by that train. The data element content definition below is a worst case assumption and would allow an HRI to adjust its closure strategy based on a train's ability or inability to react. A simpler definition would provide only closure time-of-day and duration.
