At Kastornoye, 2 railway lines are crossing each other. The first one is the line Moscow – Yelets – Valuyki built in 1897, the second one is the line Kursk – Voronezh built in 1894. This gave the city a strategic importance, which led to 2 important battles during the 20th century around the city. The first one was the Voronezh–Kastornoye operation (1919) during the Russian Civil War. The second one was the Voronezh–Kastornoye operation (1943) during the Second World War.
