I have been looking for a movie that aired on showtime, hbo, or cinemax in the 1980's. It had snakes in it that were accidentally thrown off a train. The movie was really scary and packed full of excitement. Please help. Thank you.

Jaws of Satan - user reviews (http://www.imdb.com/title/tt0082580/usercomments?)
If not, can you add any other information about the film?
