Old railways, new borders. The impact of treaty of Trianon on Western Transdanubia network (1918–1924)

The Great War and Trianon opened a new chapter in the history, not only of the Kingdom of Hungary, but also of Western Hungary. Besides dividing up the counties of Sopron, Moson and Vas, the newly re-drawn borders also split up most of the railway lines running within them as well. From the territory sliced from the three counties, the previously non-existent province of Austria, Burgenland, was established in 1922. In many cases, the new demarcation lines followed boundaries of old districts or settlements, but it was rare to find natural boundaries among them. As a result, between the two World Wars, the use of the affected railway tracks began to change similar to several contemporary Central European cases, with the exception of GYSEV (Győr–Sopron–Ebenfurth Railway Company), which could remain in its original form. This research paper aims to examine how the shift of borders in this region affected railway transport. It is based on the local historical literature on the railway, regional history and primary resources.
