Vlak u snijegu (English: A Train in the Snow), first called Djeca Velikog Sela --"The children of Veliko Selo") is a children's novel written by Croatian novelist Mato Lovrak (1899–1974), then a young schoolteacher inspired by actual events, in 1931.
At the suggestion of their teacher, fourth grade schoolchildren in imaginary "Jabukovac, near Veliko Selo", create an association and organize a field trip to the nearby town.
Another novel by Mato Lovrak, Družba Pere Kvržice ("Pero Kvržica's gang") was the basis for a film with the same title.
The main actors were Slavko Štimac (as Ljuban), and Gordana Inkret (as Draga) and Željko Malčić (as Pero), both from the "Franko Vinter" Elementary school in Bjelovar.
The theme song "Kad se male ruke slože" ("When little hands join together"), written by popular singer Arsen Dedić, is a tale of friendship and solidarity.
