One the way back from Brooksville drove the long way back up 301 to Ocala hoping to catch trains. Caught the tail end of 2 both southbound then spent a good hour driving around the mess Ocala has become before catching Q604. Saw Q604 again on the Folkston webcam 4 hours later as it went through there. Also saw this thing at Wildwood. Maybe for ballast? Cant be for snow.
