Ottoman Navy. In 1875, the Ottoman Navy had 21 battleships and 173 warships of other types, ranking as the third largest navy in the world after the British and French navies. His passion for the Navy, ships and sea can be observed in the wall paintings and pictures of the Beylerbeyi Palace on the Bosphorus strait in Istanbul, which was constructed during his reign. However, the large budget for modernizing and expanding the Navy (combined with a severe drought in 1873 and incidents of flooding in 1874 which damaged Ottoman agriculture and reduced the government's tax revenues) contributed to the financial difficulties which caused the Porte to declare a sovereign default with the "Ramazan Kanunnamesi" on 30 October 1875. The subsequent decision to increase agricultural taxes for paying the Ottoman public debt to foreign creditors (mainly British and French banks) triggered the Great Eastern Crisis in the empire's Balkan provinces. The crisis culminated in the Russo-Turkish War (1877–78) that devastated the already struggling Ottoman economy, and the establishment of the Ottoman Public Debt Administration in 1881, during the early years of Sultan Abdülhamid II's reign. The first Ottoman railroads were opened between İzmir–Aydın and Alexandria–Cairo in 1856, during the reign of Sultan Abdulmejid I. The first large railway terminal within present-day Turkey, the Alsancak Terminal in Izmir, was opened in 1858. However, these were individual, unconnected railroads, without a railway network. Sultan Abdulaziz established the first Ottoman railway networks. On 17 April 1869, the concession for the Rumelia Railway (i.e. Balkan Railways, Rumeli (Rumelia) meaning the Balkan peninsula in Ottoman Turkish) which connected Istanbul to Vienna was awarded to Baron Maurice de Hirsch (Moritz Freiherr Hirsch auf Gereuth), a Bavaria-born banker from Belgium. The project foresaw a railway route from Istanbul via Edirne, Plovdiv and Sarajevo to the shore of the Sava River. In 1873, the first Sirkeci Terminal in Istanbul was opened. The temporary Sirkeci terminal building was later replaced with the current one which was built between 1888 and 1890 (during the reign of Abdülhamid II) and became the final destination terminus of the Orient Express. In 1871, Sultan Abdulaziz established the Anatolia Railway. Construction works of the on the Asian side of Istanbul, from Haydarpaşa to Pendik, began in 1871. The line was opened on 22 September 1872. The railway was extended to Gebze, which opened on 1 January 1873. In August 1873 the railway reached Izmit.
