It is usually unwise to cross the path of a train at the same time as a train is crossing. In certain cases, however, such an action is not too terribly unsafe.
Ponder this lengthy arrangements of fuzzy caterpillars crossing a hilltop path. Lined up head to tail, each caterpillar is a car hitched on to a long train. Each car is part cargo and part engine. This train displays remarkable capabilities to split, re-connect, divide into multiple paths and rejoin into one.
Bonus points go to anyone who can count the total number of caterpillars on this train.
