Determine where you will position your end track. Measure the width and length of the end track with a measuring tape and transfer the measurements to the flooring with a pencil. Draw an outline of the end track on the surface of the floor using a metal straightedge as a guide.
Remove a section of base molding with a pry bar to expose the edge of the wood flooring. Measure the height of the wood flooring with a measuring tape to determine the depth of the cut. Replace the base molding.
Fit a router with a spline slot cutter, which contains three carbide blades for cutting wide grooves in wood. Set the router depth to the height of the wood flooring.
Place the router at one edge of the end track. Turn on the router and follow along the outline of the end track to cut the track into the wood flooring. If necessary, continue passing the router along the interior of the track area until it is the correct size.
