Wrocław Świebodzki–Zgorzelec railway

The Wrocław Świebodzki–Zgorzelec railway (Polish: linia kolejowa nr 274; German until 1945: Bahnstrecke Breslau Freiburger Bahnhof–Görlitz) is a railway line in the Lower Silesian Voivodeship in south-western Poland. It runs from Wrocław Świebodzki through Jaworzyna Śląska, Wałbrzych, Jelenia Góra and Lubań Śląski to Zgorzelec on the German border. In the Polish railway register, it is designated as line no. 274.^[1]

The present line was created in stages in the nineteenth century. Its easternmost section, between Breslau and Freiburg in Schlesien, was opened in 1843 by the Breslau–Świdnica–Świebodzice Railway, while the western and mountain sections were developed later as part of the Silesian Mountain Railway.^[2][3]

From Wrocław the railway runs west across the Silesian plain by way of Smolec, Kąty Wrocławskie, Żarów and Jaworzyna Śląska. It then enters the Wałbrzych conurbation, serving Świebodzice, Wałbrzych Szczawienko, Wałbrzych Miasto, Wałbrzych Fabryczny and Wałbrzych Główny.

West of Wałbrzych the line traverses more difficult terrain in the Sudetic foreland. This section includes numerous embankments, bridges and tunnels, including the former Schönhuter Tunnel site and the still extant Wojanów Tunnel.^[4]

The line continues through Marciszów and the upper Bóbr valley to Jelenia Góra, then through Stara Kamienica, Gryfów Śląski, Lubań Śląski and Mikułowa to Zgorzelec, where it meets the border crossing toward Görlitz.^[5]

The route developed out of several railway projects in Lower Silesia. The first part, from Breslau to Freiburg in Schlesien, was inaugurated on 29 October 1843.^[6]

During the following decades the line was extended westward through the Sudetic foothills and the Jelenia Góra basin toward Lauban and Görlitz. In the German period it formed an important regional and long-distance railway linking Breslau with the industrial districts around Waldenburg, the mountain resorts of Lower Silesia and Upper Lusatia.^[7][8]

After 1945 the railway became part of the network of Polish State Railways (PKP). In the post-war decades its infrastructure was altered in several places, and some sections lost their former double-track character. Since the early twenty-first century, major modernisation works have been carried out, especially on the Wrocław–Jelenia Góra section.^[9]

According to PKP PLK documentation, line 274 is a first-class railway line. It is partly double-track and partly single-track, and the section from the Wrocław end of the line to Lubań Śląski is electrified at 3 kV DC.^[10]

The line is notable for the number of engineering structures on its central mountain section, including several bridges over the Bóbr, the Wojanów Tunnel, and the cross-border Neisse Viaduct at Zgorzelec.^[11]

The line carries regional passenger traffic and freight traffic. It is served in particular by regional trains of Koleje Dolnośląskie, including services linking Wrocław with Jelenia Góra and Zgorzelec, as well as cross-border trains to Görlitz.^[12]
