తల నుండి పొగ చిమ్ముంది, భూతం కాదు. కన్నులెర్రగా ఉండు రాకాసి కాదు. పాకిపోవుచుండు పాము కాదు?

Explanation

This riddle describes a train: smoke comes from its head (locomotive), it's not a ghost; it has red eyes (signal lights), it's not a demon; it hisses while moving, it's not a snake. The riddle is clever because it attributes supernatural or animal qualities to a modern vehicle, making the listener think of mythical beings before arriving at the mundane answer of a train.
