William Shatner & Yvette Mimieux in Disaster on the Coastliner (1979)

The glut of disaster movies in the 70's included a second tier of television films. In this one, a deranged computer programmer (Paul L. Smith) distraught at the loss of his wife and child, reprograms a rail system's computer to put two trains on a collision course, endangering the lives of the passengers. Will they be able to circumvent disaster? Along for the ride is charming grifter, Stuart Peters (Shatner) and an unhappy Paula Harvey (Mimieux). At home base, trying to solve the problem are Al Mitchell (Lloyd Bridges), Estes Hill (Raymond Burr) and Roy Snyder (E. G. Marshall). Though a fromage fest, this film has a lot of entertainment to offer. If you're a fan of bloated, second tier star spectacles, give it a try.
