No, but rather than use such short sections, I would buy one of the long sections available (they are about 3 feet in length) and cut it down to the length of one and a quarter sections. Less joints, more stable than very short pieces..
Pick yourself up a Dremel tool and cutting wheels, makes cutting track easy and us useful for many other projects too.
My first layout had these little oddball tracks in everywhere and it caused me nothing but headaches until I replaced them. Lionelski is right.
