Małkinia is a railway junction. There, the main line between Warsaw and Białystok crosses with the secondary-importance connection Ostrołęka - Siedlce. During World War II the Nazi Treblinka extermination camp was located nearby. Victims were often held in locked trains at the Małkinia railway station awaiting transport into the camp.
