A computer system configured to use train telematics data to reduce risk of accidents via a mobile device traveling within a vehicle may be provided. The mobile device may be configured to (1) receive train telematics data associated with a train that includes GPS location, speed, route, heading, acceleration, and/or track data; (2) determine when, or a time period of when, the train will pass through, be passing through, or be within a predetermined distance of a railroad crossing based upon the train telematics data; (3) determine an alternate route for the vehicle to take to avoid waiting at the railroad crossing; and (4) cause display of the alternate route on a display of the mobile device or a vehicle navigation system to allow the train to pass and to avoid train-vehicle collisions. Insurance discounts may be generated based upon the risk mitigation or prevention functionality.
