fwe-train_data

This data flow contains time critical data about an approaching train and is provided to HRI at the roadside by railroad owned and maintained equipment and/or communications networks. This data, if available, will be provided concurrently with the approaching train announcement and must include data sufficient for the HRI to determine crossing close time, and the anticipated closing duration. A train identification is required to allow the HRI to manage multiple train arrivals at a single crossing within short time intervals.
