As a train approaches the Smithfield Station heading westbound to Fort Worth, the crossing gates at Smithfield and Holiday all go down. If it is a freight train or the Grapevine Vintage Railroad, the train will continue through and the gates at each crossing will come up as soon as the train passes. If it is a TEXRail train that stops for boarding at the station, the gates at the crossings may go back up while the train is stopped. Then they go back down when the train leaves the station again. Trinity Metro TEXRail is in the process of reviewing crossings to determine what changes can be made to minimize interruptions to traffic flow while still maintaining federal safety requirements.
