As a Moments subpage, all spoilers are unmarked as per policy. You Have Been Warned.
- The beginning when, after sending a boy to fetch two symmetrical eggs for his breakfast, Hercule decides the boy may have the eggs instead. Crosses over into Funny Moments.
- Poirot also makes a point of assuring the boy that he's not to blame for the eggs not being symmetrical, and that it's the chicken's fault.
- The little moment when Poirot indulges in the baker's bread coming fresh out of the oven, inhaling rapturously and calling the baker an artiste.
- A minor moment during the opening: Professor Hardman loudly refuses to sit with Dr. Arbuthnot because he believes in "keeping different kinds separate". When Mary protests, he points to her dining table and says it would be like mixing red wine and white. Mary promptly picks up her glass of red wine, empties it into the glass of white wine, and takes a long drink: "I do like a good rosé." What makes this especially heart-warming? She's doing this in defense of Dr. Arbuthnot, whom she has feelings for. Doubles as a Moment of Awesome.
- Later, when Hardman is exposing his true identity, he makes a point of apologizing for his comments on race, even though Dr. Arbuthnot isn't present.
- A man like Poirot who travels a great deal can't have much in the way of belongings, but he does have a well framed picture of his beloved Katherine. Also counts as a Tear Jerker.
- Part of the reason Bouc insists Poirot take on the case of Ratchett's murder is out of genuine concern for the Spanish-surnamed Marquez and black Dr. Arbuthnot, believing that without strong evidence the police would be likely to convict either of them as the killer. Though he thinks of himself as a horrible person, this shows that he shares Poirot's view of justice.
- Dr. Arbuthnot's Race Lift comes with the admittance that Colonel Armstrong was the one who afforded him the rare opportunity for someone of his race at the time to practice medicine, noticing his delicate hands and sense of care while they were fighting together in the War.
- During The Summation, Hardman admitting he was mutually in love with the Armstrong family's maid. He has a fond, bittersweet smile upon recollecting what a sweet woman she was. According to Hardman, she fell in love with him and he humbly insisted she date a younger man her age instead of him. But she was on time for every date... up until her wrongful accusal.
- The moment during The Summation when Poirot realizes that it was all of them, together, who killed Ratchett. The scene switches to the conspirators watching a home movie of the Armstrongs, the same one Col. Armstrong was watching before he shot himself. It's hard not to feel bad, but overall, it's poignantly heartwarming how all these people from different walks of life find common ground with their shared tragedy.
- Linda Arden claiming that despite them all murdering Ratchett, everyone (sans herself) are still good people. In the very least, she believes "they can be good again".
- Linda was willing to get painfully stabbed just to save McQueen. She could have easily let him take the fall but refused to abandon him.
- The fact that none of the suspects blame any of the others for what happened to Daisy or to the maid. They understand that they were victims too.
- The montage of various passengers following The Summation. The Count and Countess get rid of the latter's sedatives stash, Dr. Arbuthnot and Mary are walking hand in hand, Princess Dragomiroff is playing cards with her maid as an equal and Mastermann consoles a forlorn Cyrus Hardman. Having dispensed justice to the man who caused them so much grief, their wounds are finally beginning to heal.
- During his voice-over, Poirot decides that he must listen, not to logic or his desire for balance, but to his heart.
- Poirot's solemn, respectful farewell to the passengers before he gets off at his stop. He tells them he's given the police the false summation of what happened to Ratchet, and they are all free. He dearly hopes they all (including himself) find peace with this lie about the murder. When the train departs, all of the suspects give Poirot one final gaze, which seems to say, "Thank you for understanding."Poirot: Ladies and gentlemen. I have understood in this case that the scales of justice cannot always be evenly weighed, and I must learn for once to live with the imbalance. There are no killers here, only people who deserve a chance to heal.
- The fact that no was willing to shoot Poirot and even attempted to talk Caroline out of it when it appeared as if she was going to during his Secret Test of Character despite the risk of them all being convicted.
