Atomic Train (1999)

Synopsis
In this made-for-TV thriller, a train hauling a cargo of radioactive waste is passing through Colorado when its brakes fail in the Rocky Mountains. The train begins rolling out of control and is headed for Denver with no way to stop it. John Seger (Rob Lowe), an agent with the National Transportation Safety Board, has to find a way to bring the train safely to a halt, and he soon learns that the stakes are even greater than he imagined -- a faulty Russian atomic bomb is also on board, which could blow the city sky high in the event of a wreck. Atomic Train also stars Kristen Davis, Esai Morales, and Mena Suvari, the latter shortly before she bolted to stardom with roles in American Pie and American Beauty. ~ Mark Deming, All Movie Guide
