Big metal bumps into big metal. There is a satisfying clink. Almost as good as the dink of cold beer bottles as we toast each other after a hot work day.
Every time I take the train from New York City to Westport, NY, the train stops in Albany to get a new engine. And so I hurry from my seat to the platform with the other train enthusiasts (12-year old boys, pot-bellied men, tourists from Japan) to watch the new engine back in and clink against the train.
Why is this moment of impact such a thrill? Because the engine is small and the train is heavy. Because the elegance and engineering of rail travel still amazes me. Because there is a satisfying clink. Cheers!
