“It's hard to use the English language. I'd rather play a tune on a horn, but I've always felt that I didn't want to train myself. Because when you get a train, you've got to have an engine and a caboose. I think it's better to train the caboose. You train yourself, you strain yourself.”

“A freshly red-painted train caboose had, for decades now, made its home on a green, little patch of the world outside of the one-room post office. Every small town that I had ever been to had had a caboose.”

“Trains are relentless things, aren't they, Monsieur Poirot? People are murdered and die, but they go on just the same. I am talking nonsense, but you know what I mean.""Yes, yes, I know. Life is like a train, Mademoiselle. It goes on. And it is a good thing that that is so.""Why?""Because the train gets to its journey's end at last, and there is a proverb about that in your language, Mademoiselle.""'Journey's end in lovers meeting.'" Lenox laughed. "That is not going to be true for me.""Yes--yes, it is true. You are young, younger than you yourself know. Trust the train, Mademoiselle, for it is le bon Dieu who drives it."The whistle of the engine came again."Trust the train, Mademoiselle," murmured Poirot again. "And trust Hercule Poirot. He knows.”

“You better be careful, I've got a ladle. You never know what a trained killer can do with an innocent-looking kitchen utensil.I don't think you're a trained killer.So should I be insulted that you think I'm an amateur killer?”

“I would like to visit the factory that makes train horns, and ask them how they are able to arrive at that chord of eternal mournfulness. Is it deliberately sad? Are the horns saying, Be careful, stay away from this train or it will run you over and then people will grieve, and their grief will be as the inconsolable wail of this horn through the night? The out-of-tuneness of the triad is part of its beauty.”

“But lassies are trained for it, in a manner of speaking; it's part of the growing-up process for them, young females. It doesn't happen with boys, just if you're a lassie, you've got to learn how not to talk; plus how not to look, you get trained how not to look. How not to look and how not to talk. You get trained how not to do things.”
