"The Finishing Line" is a 1977 British safety movie about encouraging kids not to play on train tracks.
That is to say, it's a horrific festival of cruelty, injury, and gory death.
The story (a short one, circa 20 minutes) is a fantasy. An imaginative boy wonders about playing games across railroads, and the film plays it out. What looks like two hundred kids compete in races, rock-throwing contests, and games of walking into onrushing trains. Casualties accumulate, tended by very bland and unmoved adults. A brass band wheezes while judges award points for accomplishments and mayhem. It's like a dark, 1970s British version of Battle Royale (2000).
