Paths of Trains with Two-Wheeled Cars

In this paper we study the following simple and mind-puzzling problem: Can a model train car, which runs along an intricate track complete a full cycle around it? In our paper a track will be represented by a simple closed curve, and the cars of our model train by segments whose end-points lie on the curve.
