Why should you check for a second train before crossing multiple sets of tracks, even after one train has passed?

Pick an answer

1. A second train can approach on another track while attention is still on the first, especially if visibility is limited
2. Only one train ever uses a crossing at a time
3. Multiple tracks make a crossing inherently safer
4. A second train is not a realistic risk once the first has passed, since most crossings are only served by a single rail line
