As the bombings in cities worsen in 1944, Lily (Beau Gadsdon), Pattie (Eden Hamilton), and Ted (Zac Cudby) are transported to live in the country. They are adopted by local teacher Annie (Sheridan Smith) and her mother Bobbie, who is Jenny Agutter back from before, and instantly become close friends with Thomas, Annie's son (Austin Haynes). The kids come across fugitive American soldier Abe (KJ Aikens) while exploring the nearby train tracks. Despite his adamant assertion that he is 18 years old, Abe is clearly in over his head. The kids must work together under Lily's obstinate leadership to make sure Abe gets home safely.
The Railway Children struggle the most with Abe's situation. The film's depiction of the prejudice Abe experiences is not subtle or delicate. Railway Children explores this complex subject in just the ways one would expect, from harsh depictions of Black troops being beaten to an ardent (but familar) monologue delivered by Abe himself. Although it is wonderful that it wants to tell this subject, it lacks the poise necessary to have an impression. As a result, the movie's emotional climax comes off as a little hollow. Although some viewers will undoubtedly applaud when Railway Children reaches its climactic climax, the proceedings have a very childish air to them.
