|"89 mm from Europe"|
The film was shot at a railway station on the Poland-Belarus border. Because there is an 89-mm (3.5-inch) difference in gauge between the standard European tracks and those of the former Soviet Union, workers jack up the trains and change the wheels to adjust. Passengers on the Paris-Moscow express (and other trains) wait it out. Not that different, I suppose, from the changeover Amtrak used to make in New Haven from diesel to electric--crossing the Pinstripe Curtain from the Red Sox to Yankee zone.
It feels like the 1950s but the film was actually made in the early 90s. You can watch 10 minutes of it below (with English subtitles) on YouTube or check out the full 12 minutes without subtitles but with credits on Vimeo.
