Factual error: The Russians stopped using steam locomotives in the 1970's. So bringing one out of retirement in 1997 to haul nuclear warheads would mean that your highly secret nuclear train would be well known among rail enthusiasts for weeks before.
The Peacemaker (1997)
Ending / spoiler
Directed by: Mimi Leder
Starring: Nicole Kidman, George Clooney, Aleksandr Baluev, Marcel Iures
The Serb leader kept a warhead and travels to NY to detonate it at the UN summit. Nicole Kidman and George Clooney catch him before he gets there, and the bomb detonates but they damage it enough that it doesn't go nuclear - the explosion and radiation is contained within a church. They hook up together for a beer.
