The neighborhood's original name was the Railway colony (Serbian: Železnička kolonija). At the beginning of the 1920s, the Ministry of Railroad started building a neighborhood for their workers. Even today, the neighborhood is filled with old trains and their parts, so its primary purpose still remains in a way.
It is located in the southern part of the municipality, at its border with the municipality Savski venac. Around the neighborhood, there are 4 forests: Košutnjak, White Palace forest, Banjica forest, and Miljakovac forest. River Topčiderka flows through the whole neighborhood. It is 8 kilometers from the center of Belgrade (~5 miles). Close to this neighborhood is the park Topčider and a forest with a similar name – Košutnjak. And in its very close vicinity is also the luxurious neighborhood Dedinje, which connects the neighborhood to Slavija, a part of Belgrade's center with the most traffic.
