Which locomotives / railcars have a great sound?

Whether it's the scale of the Taurus (182), the champagne cork-like popping of the 141 (which is why it's also called "Knallfrosch") or the sound of the 425, which is (sometimes affectionately, sometimes disparagingly) called "Squeaky": Some locomotive and railcar series have unique sounds. What other locomotives/railcars sound good? What other examples come to mind?
