The Priemerburg-Plaaz railway is a single-track, electrified branch line in the German state of Mecklenburg-Vorpommern.

After running through a wooded area, it passes through Glasewitz station, which closed in 1993 and has left few traces.

The Lloyd Railway connecting Neustrelitz and Rostock was opened in 1886, but it by-passed the town of Güstrow.

The importance of the line was limited to local traffic, especially after 1887 when the direct connection from Güstrow to Rostock over the Güstrow–Schwaan railway went into operation.

The importance of the line for freight traffic grew with the construction of the new port of Rostock up to 1960.

After a year and half of closure due to the renovation of the adjoining section of the Lloyd Railway, trains have run since June 2007 between Rostock, Plaaz and Güstrow every two hours; on Monday to Friday mornings and afternoons services were hourly.
