Abstract: A system and method are disclosed to provide train detection and alerts. Embodiments include monitoring train status data, detecting a presence of a train based on the train status data, capturing current train data and converting the current train data and mapping device location data from one or more mapping devices into train metrics. Embodiments estimate an arrival time of the train at a railroad crossing and a duration of the train at the railroad crossing, check the current train data for errors, apply rules to the current train data to validate the current train data and generate an alert in response to the rules being satisfied. Embodiments display the alert on the one or more mapping devices to notify one or more corresponding users of the one or more mapping devices of the presence of the train.
