If you didn't stop on top of the navigation icon, then you may have to move up more until it sees your train
Be aware that on subsequent stops there are no "go" indicators... I don't recall even getting a whistle. Schedule is tight so you can't afford to wait too long for a "go" that doesn't come. That's my recollection.. you're experience may vary
