As a train approaches the Smithfield Station heading east to Grapevine, the crossing gates at Smithfield, Davis and Main 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, it will stop at the station and board passengers. The gates at Davis and Main usually stay down while the train is boarding. The crossing gates on Davis and Main are down for about 3 to 4 minutes for each eastbound TEXRail train. Once the crossing gates go up, traffic on Davis gets a green light first, followed by Main Street. 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.
