The line was closed and disassembled in 1919, in the aftermath of World War I, reopening in 1924.

Between the end of World War I and the end of World War II, the stations from Garczegorze to Rybno Kaszubskie were in Germany while the five stations from Zamostne to Wejherowo were in Poland.

The railway tracks remain in place, but years of neglect mean the line is currently impassable.

The decision to stop the construction of said nuclear power plant in 1990 was a major factor in the downfall of line 230.

In 2002 plans were put forward to re-open the line, to be run by the Gniewino and Choczewo communes, but nothing came of this.
