This belonged to the concentration camp of Mittelbau-Dora, which established field offices in September 1944 in, inter alia, Quedlinburg and Traunstein.

The importance of the freight and marshalling yard fell with the decline of the metal industry in the Quedlinburg station area at the beginning of the 1990s.

The last infrastructure of the former Quedlinburg freight yard disappeared with the reconstruction of the southeastern part of the station by the Harz Narrow Gauge Railways.

In the spring of 2009, Mitteldeutsche Baustoffe GmbH was commissioned to rehabilitate the already disused and isolated second track between the Magdeburger Straße level crossing and the former Groß Orden siding.

Goods from Bode Kieswerk in Ditfurt, two kilometres away, and from the quarry in Rieder, twelve kilometers away, are transhipped from trucks to trains here.

[12] The 126 tonne heavy diesel locomotive (Voith Maxima 40 CC) that hauled this traffic was named Quedlinburg on 27 May 2011.

These were produced by the Ferdinand Müller stained glass factory and represent views of the castle hill (Schlossberg) and the town hall (Rathaus).

The third signal box in Quedlinburg was located in the area of Quedlinburg-West (Qw) and was responsible for the Quäke marshalling yard.

The gatekeepers worked at Gernröder Weg, at the Quedlinburg Ost, Mitte and West signal boxes and at the Magdeburger Straße crossing.

As part of the conversion of a line to be incorporated in the Harz narrow gauge railways in 2005/2006, the affected level crossings were converted to automatic systems with half barriers.

Necessary renovation work on the more northeastern level crossings failed to eventuate for a long time because Deutsche Bahn would not commit to carry it out or provide a share of the finance.

For example, Magdeburger Straße (formerly B6, now a feeder to B6n) was completely renovated with footpaths and cycle paths on both sides except in the area of the level crossing.

The level crossings of Magdeburger Straße, Badeborner Weg and Frachtstraße were to be redesigned in the spring/summer of 2013 as part of the flashing light program.

Full barriers with flashing lights are still in operation only on Frachtstraße (as of February 2014), because there are safety issues in relation to the entry of trucks to the adjacent supermarket.

The hall of the entrance building once accommodated numerous counters, timetables, small shops, later the Mitropa restaurant, a station barber, a newsstand and ticket machines.

After Deutsche Bahn withdrew from ticket sales, Q-Bus Nahverkehrsgesellschaft took over a counter and has since sold tickets for Deutsche Bahn, Transdev (HEX), the trains of the Harz Narrow Gauge Railways, the buses of Q-Bus and Verkehrsgesellschaft Südharz (only for buses from the Harz district and the Salzland district).

Several sculptures and installations were established, but most had to be removed during the renovation of the parking area for the Harz Narrow Gauge Railways.

[20] A transfer of the node from Quedlinburg to Thale, as was planned in 2005,[21] has now been rejected due to the need to provide interchange with the HSB.

Services on the Magdeburg–Thale line have been operated since 11 December 2005 for an initial twelve years by Transdev Sachsen-Anhalt under the name of HEX (Harz-Elbe-Express).

To do so, Mitteldeutsche Baustoffe GmbH built a new 2000 metre track parallel to the main line, allowing 590 metre-long trains to be handled.

In 2003, a signal box fire in Ballenstedt Ost was used as an opportunity to stop operations initially between Gernrode and Ermsleben.

Even before the suspension of traffic on the line to Frose, there were plans to extend the narrow-gauge Selke Valley Railway (Selketalbahn) from Gernrode to Quedlinburg to increase its attractiveness.

[25] Due to the well-preserved embankment, the construction time was just under a year, with almost all level crossings modernised or replaced by automatic systems.

Parts of the line were shut down as they were severely damaged by the excessive loads on freight trains from Rübeland during the closure of the Halberstadt–Blankenburg railway.

From 1975, the tracks were dismantled between Thale and Weddersleben; in the Quedlinburg area freight traffic was operated by the wagon factory (RAW) until 1993.

In the 2019 timetable, Quedlinburg station was served by the following lines: Local transport in the Harz district is operated by Harzer Verkehrsbetriebe.

Long-distance bus operator, MeinFernbus Flixbus serves Quedlinburg on routes 051 and 129 several times a day.

"Bike-and-ride" places are available in sufficient numbers both at platform 1 and in the parking lot of the Harz Narrow Gauge Railway (HSB).

The halt, located on the Frose–Quedlinburg railway directly next to state route 239 (Quedlinburg–Bad Suderode), was opened on 2 October 1936 under the name of Römergraben to serve the nearby airfield in Quarmbeck.

The halt (a request stop on the Selke Valley Railway) is not connected by a footpath to the settlement of Quarmbeck, so pedestrians have to use the road for about 450 metres.
