1841), and in Floridsdorf (Floridsdorf Locomotive Factory, founded in 1869). The Hungarian factories producing rolling stock as well as bridges and other iron structures were the MÁVAG company in Budapest (steam engines and wagons) and the Ganz company in Budapest (steam engines, wagons, the production of electric locomotives and electric trams started from 1894). and the RÁBA Company in Győr. Shipbuilding The largest shipyard in the dual monarchy and a strategic asset for the Austro-Hungarian Navy was the Stabilimento Tecnico Triestino in Trieste, founded in 1857 by Wilhelm Strudthoff. Second in importance was the Danubius Werft in Fiume (present-day Rijeka, Croatia). Third in importance for the naval shipbuilding was the Navy's own Marinearsenal, located at the main naval base in Pola, present-day Croatia. Smaller shipyards included the Cantiere Navale Triestino in Monfalcone (established in 1908 with ship repairs as the main activity, but went on during the war to manufacture submarines) and the in Fiume. The latter was established in 1854 under the name Stabilimento Tecnico Fiume with Robert Whitehead as the enterprise's director and the purpose to produce his torpedoes for the Navy. The company went bankrupt in 1874 and in the following year Whitehead bought it to establish the Whitehead & Co. Next to torpedoes the company went on to produce submarines during WWI. On the Danube, the DDSG had established the Óbuda Shipyard on the Hungarian Hajógyári Island in 1835. The largest Hungarian shipbuilding company was the Ganz-Danubius. Infrastructure Telecommunications Telegraph The first telegraph connection (Vienna—Brno—Prague) had started operation in 1847. In Hungarian territory the first telegraph stations were opened in Pressburg (Pozsony, today's Bratislava) in December 1847 and in Buda in 1848. The first telegraph connection between Vienna and Pest–Buda (later Budapest) was constructed in 1850, and Vienna–Zagreb in 1850. Austria subsequently joined a telegraph union with German states. In the Kingdom of Hungary, 2,406 telegraph post offices operated in 1884. By 1914 the number of telegraph offices reached 3,000 in post offices and further 2,400 were installed in the railway stations of the Kingdom of Hungary. Telephone The first telephone exchange was opened in Zagreb (8 January 1881), the second was in Budapest (1 May 1881), and the third was opened in Vienna (3 June 1881). Initially telephony was available in the homes of individual subscribers, companies and offices. Public telephone stations appeared in the 1890s, and they quickly became widespread in post offices and
