Which Way Is This Train Going?

In which direction does this #train move? From which end of the tunnel is it arriving from? It might be both! Check if you can “see” a different direction each time you look at it? If you stare long enough, you might even make the train change its course. Today’s illusion works in the same manner, our famous Spinning Girl does. After all, there is no definitive answer, since the animation loops through just a few frames. On the other hand, if you recognise the station, you just might know the true answer after all ;)
