Terror Train (1980)

A slasher killer loose on a steam train! A group of college kids hold their end of year party on a sleeper train, much debauchery is planned at night. What isn't planned is their ex-classmate Kenny (Derek MacKinnon), whom was sent to an asylum a few years ago after a prank went wrong, also joining the party and beginning his revenge with the help of various sharp objects.

While Alana (Jamie Lee Curtis) and Doc (Hart Bochner) are watching The Magician (David Copperfield), the body count starts to add up much to the consternation of the train conductor (Ben Johnson). Once the actions of Kenny are known a bitter and bloody battle for survival begins aboard the train as it steams through the night...

Although the slasher revenge theme is not too original, the setting is quite novel and adds an interesting dimension to the thrills and scares. The Magician adds a bit of mystery and cheese.
