See the railway viaducts from above

In the Olomouc Region, we created 3D visualizations of historical buildings.

The Přerov-Bohumín railway line, nowadays also referred to as line 271, was an important transport structure already in the 19th century. At that time, it belonged to the famous company of the privileged Northern Railway of Emperor Ferdinand, and beautiful period railway bridges were built on it. The Hranice and Jezernice viaducts were even declared a cultural monument of the Czech Republic in 2007.

Let's take a look at the individual objects separately.

The Jezernice viaduct actually consists of 2 originally brick bridges that were built in the middle of the 19th-century side by side. It rises above the Jezernice stream valley between the Lipník nad Bečvou and Drahotuše bus stops and is almost 427 m long. A total of 42 major and minor arches have been completely reconstructed and the viaduct was awarded the 2001 Bridge Work of the Year award by the Ministry of Transport of the Czech Republic. Frost-resistant bricks were used and the reinforced concrete arch was anchored into the brick arches with a metal net.

The Hranice viaducts refer to three parallel railway bridges that arch over the Velička River near the Hranice na Moravě railway station. The first two brick structures are interconnected by concrete slabs that cover the gaps between them, where the joined piers touch. The third structure, i.e. the concrete bridge, is connected to them by a footbridge in the place of the gaps.
Our colleagues Ondřej Kočí and Ondřej Filip first surveyed both viaducts in the field from a height and then Radim Holub processed them as 3D visualizations. What devices were used and why are 3D visualizations created? Read the comments directly from our specialists.

The route between Lipník nad Bečvou and Přerov was originally a single-track line. In the middle of the 20th century it was converted into a double-track line and today it is also fully electrified. It belongs to the so-called II. transit railway corridor, which is the main long-distance railway line between Breclav and Petrovice u Karviné.

Take a look at the important and historically significant sections on this route and come and fly over the two viaducts.
