In 1867, the issue of building a line from Ząbkowice Śląskie evolved towards a return to the project of a railway connection between Austria and Wrocław, leading, among others, through Kłodzko and Ząbkowice Śląskie. On 5 August 1867, an interstate agreement was ratified in Berlin, regulating the matters of establishing a railway connecting Silesia with the Czech Republic. According to the provisions, the Prussian government undertook to grant a private company a concession to build a railway on its territory and inform the Austrian side about it. Then, a condition was set for the Austrian side to deliver - independently or through a licensed company - a section of the line from Usti nad Orlici to Międzylesie at the same place and time as the Prussian side, at the same time giving an ultimatum to take the first steps in this direction within six months of ratifying the treaty. In the event of a breach of the provisions by the Austrians, Prussia reserved that it would direct the Prussian railway company to build and operate the Austrian section, bypassing the will of that state. This position raised objections from the Austrian side, but this was of no importance in the face of Prussia's military victory in the recent war. In 1868, Prussia began negotiations with the Upper Silesian Railway, which, in addition to the aforementioned pioneering connection between Wrocław and Upper Silesia, operated a cross-border line from Wrocław to Poznań, launched in 1856. Of no small importance was the fact that the state owned 20 percent of the shares in the company, and from 10 October 1856 the company was placed under state management (the Royal Directorate of the Upper Silesian Railway in Wrocław). However, the company's affairs were not the exclusive competence of the Directorate and were dependent in many matters on the decisions of the supervisory board. On 22 September 1868, the general meeting of shareholders of the Upper Silesian Railway convened in Wrocław initially rejected by a majority, and in a second vote by over half of the votes. This was caused, despite the provisions of the Berlin agreement, by the continued reluctance of the Austrian side to build a railway on the other side of the border. However, when in December 1868 the authorities in Vienna informed the Wrocław consulate that they intended to grant a concession for the construction of their section of the line, the reason for the opposition ceased to exist. The railway line from Wrocław to Międzylesie was built and put into service in stages: in 1871 on the section Wrocław Główny – Strzelin, 1872 – Strzelin – Ziębice, 1873 – Ziębice – Bardo Śląskie (bypassing Ząbkowice Śląskie), 1874 – Bardo Śląskie – Kłodzko Główne, 1875 – Kłodzko Główne – Międzylesie. In the years 1874–1875, a line from Ústí nad Orlicí to Międzylesie was built, tangent to today's line no. 276. The first train crossed the border, then Prussian-Austrian, on 15 October 1875. Further history of the line Before 1945, the line on the section from Wrocław to Krosnowice Kłodzkie was a double-track. After 1945, one track on the Strzelin–Kamieniec Ząbkowicki section was dismantled. In the years 1991–1994, the Wrocław Główny–Międzylesie section was electrified. In 1991, the electrified Wrocław–Kłodzko section was put into service, and on May 26, 1994, the first electric train to Międzylesie ran. source: wikipedia
