History YMMV / HorrorExpress

* JustTrainWrong: The train interior sets and the train model used for the exterior shots were the same sets used for the 1972 biopic of Pancho Villa. Just as expectable, they barely resemble the Imperial Russian express trains [[TheEdwardianEra of the 1900s]]. This turns in a plot hole as the monster cuts the electric lighting wire to be able to kill the armed Cossacks in the dark. Imperial Russian rail cars usually had [[SchizoTech lanterns with candles or oil lamps inside]] so it had to smash by hand each and every lamp to achieve this.
* OneSceneWonder: Telly Savalas turns up close to the end of the film and stops the story cold with his portrayal of swaggering, vodka-swilling Tsarist Captain Kazan.

* CompleteMonster: The [[BigBad unnamed alien]] is an EnergyBeing who, unfettered in its course to escape the planet, agonizingly burns out the brains of countless people on the titular train to gain their knowledge. The alien murders many people, innocent and otherwise, on the train, massacring the depraved Captain Kazan and all of his men and even nearly killing some [[WouldHurtAChild children]] sleeping on the train. The alien cheats death by [[BodySurf leaping from body to body]] to sustain itself, murdering anyone who finds out its secret and even barely regarding its loyal lackey after he lays down his life for the alien.

* NeutralEvil: The alien uses whatever means it has at its disposal to reach its goal of surviving on Earth and ultimately returning to its home planet. Though killing innocent people isn’t the end in and of itself, the creature is more than willing to do so in order to obtain knowledge and materials necessary to achieve its goals.
