Ay Caramba!!!!!!!!!!!!!!!!! The honk reminds me the days of good ol' steam :) and it was not an extended single honk but more of a short sweet and rising honking as if dusting off the tracks ahead in short but sweeeeeeet bursts and damnnnnnnnnnnnnnnnnnnnnnnn......came outta nowhere and disappeared equally at a thundering speed.Wooooooooooooshh!
