Once the decision had been made and the optimal route had been studied, the first excavations were recorded in September 1868, at the area of the current railway station in Trzemeszno.

The locomotive depot has been rebuilt several times and it has now become a roundhouse, one of Europe's largest with 24 roads coming from it.

[1] In the years 1908 to 1911, as a result of numerous transformations both in the late nineteenth and early twentieth century, the technical and operational activity at the station expanded.

In 1940, as a result of the meeting of the Special Committee approved the plan "Otto", which aimed at the restoration and reconstruction of railways, modernization and expansion of railway stations and in the case of Gniezno modernization and expansion of the roundhouse.

But the same program "Otto" did not finish there as the freight yard at Gniezo was expanded to relieve Poznan.
