On 18 October 1847, there was a continuous line from Breslau to Cracow for the first time when the Upper Silesian Railway was linked to the Cracow-Upper Silesian Railway. With the completion of the railway within Breslau on 3 February 1848 that connected its termini, there was now a continuous rail link from the Rhine to the Vistula And with the closure of a short gap between the William Railway in Upper Silesia and the Emperor Ferdinand Northern Railway in Austrian Silesia on 1 September 1848, the first contiguous Central European network was formed, reaching as far as Deutz, right of the Rhine, in the west, Harburg in the north, Warsaw and Cracow in the east and as far as Gloggnitz at the northern foot of the Semmering Pass in the south. Among the northern lines there were still small gaps in Berlin and Hamburg.
