The drive system includes an engine mounted on the chassis deck, front and back pairs of wheels and a pair of drive track assemblies mounted on the chassis front and back ends. The application system includes an actuating subassembly for selectively engaging railroad ties and a sprayer subassembly for spraying preservative on railroad ties in response to engagement by the actuating subassembly. A method of servicing railroad ties includes the steps of removing a rail from one side of a railroad track, exposing connection areas where the rail attaches to the railroad ties, driving a vehicle with preservative along the railroad track and applying preservative to the connection areas in response to engagement of the railroad tracks by an actuating subassembly.
