Atomic Train (1999) - Original Trailer Atomic Train is a 1999 action-thriller film about an accidental nuclear explosion destroying the city of Denver. It was originally broadcast on NBC as a two-part miniseries. A waste disposal company has a Russian nuclear bomb to transport, and an employee decides to save money by concealing it on a freight train. This train is also loaded with hazardous and flammable chemicals including metallic sodium which spontaneously ignites on contact with water. The train suffers a brake failure and becomes a runaway heading for Denver. John Segar, an NTSB investigator, boards the train and with the assistance of the railwaymen tries various ways to stop the train. Several ideas are tried, such as coupling a following train to the caboose (the coupling mechanism on the caboose breaks), a derailing attempt (after it is revealed the catastrophe the chemicals would cause if ignited) in which a helicopter narrowly avoids being hit, and finally, an attempt at manually activating the brakes (via hitting a part of the engine mechanism with a wrench). The final attempt works successfully, but is short-lived. The following rescue train, unaware of the freight's slowing, speeds forward and crushes the caboose (killing an injured member in the process). The force disengages the brakes, causing the train to speed up once again. Meanwhile, Denver residents are struggling to collect their families and then leave town, despite rioters and gridlock. Realizing that there is no way to stop it, John and the engineer (who was initially reluctant) abandon the train by jumping off before it can speed up too much. The train derails and becomes a terrific wreck. Discovering the now highly unstable bomb on-board, firefighters struggle to put out the fire at the crash site. After realizing that metallic sodium is on the train, the firefighters and NEST teams retreat to evaluate a strategy. In the mean time, all fire fighting aircraft are grounded. The misinterpretation of a radio call to a water bombing helicopter leads it to dump its load of water onto the wreck. Water comes into contact with the metallic sodium, which explodes and in turn causes the nuclear bomb to detonate. The blast causes severe damage throughout Denver and releases an electromagnetic pulse. No cars work, electricity is down and anything with a computer is shut down. After the Blast, Denver lays in ruins, John (who made it back to town via helicopter) then attempts to get his family out of Denver before nuclear fallout starts. After finding a working car, John eventually reunites with his family at a refugee camp in Kansas. Enjoy!
