The Katy continues about 3-miles north of the St Charles trailhead, where one encounters a grassy unfinished railroad bed, which appears to be the end of the trail. However, most of the Machens section is completed beyond that point except for that 3-mile section of grassy, cowpath like riding. Supposedly, that unfinished section is passable although not really open yet.
