Spectacular train explosions have been employed by filmmakers to convey a tense atmosphere of the military conflict, portrayed on the silver screen. Yes, a large-scale disruption of railways is one of the most convincing methods to vividly demonstrate the destructive nature of the war. Here are some examples of this special effect, which has been expecially useful for films about WWII.
Soviet war drama «Секретарь райкома» (The District Secretary, directed by Ivan Pyryev, produced by Mosfilm Studios, 1942) tells us about Communist-led guerilla fighters, who carry out terrorist acts against the Nazis behind enemy lines. Incidentally, special effects in this movie were staged by a cinematographic wizard — Alexander Ptushko. British-American World War II film The Bridge on the River Kwai (directed by David Lean, produced by Columbia Pictures, 1957) contains a culminative scene, where British POWs, held captive by the Japanese, blow up the bridge while the enemy train has been passing it. A Soviet-Polish-East German-Italian-Yugoslav film series about the World War II «Освобождение» (Liberation, directed by Yuri Ozerov and Julius Kun, produced by Mosfilm Studios, DEFA-Babelsberg, ZF-Start, PRF-ZF, Avala Film, and Dino de Laurentiis Cinematografica, 1970-1971) also magnificently shows, how the Nazi’s train has been destroyed.
