Mudryona (Ukrainian: Мудрьона; Russian: Мудреная, Mudryonaya, formermly Dzerzhynska) is a station on the Kryvyi Rih Metrotram. Originally opened on 26 December 1986, the present structure dates to 23 February 1988. This confusion is best described, in the Tram arrangement and necessity to have a reversal ring for a terminus. The original one, which is located just before the station, was opened as a temporary terminus of the first stage.
The present structure was opened in 1988, however as the second stage, due to technical problems, could not open at once, two three-car shuttles were in use on each track between the ring and Budynok Rad station. In 1989, after the opening of the second stage and the ring at Kiltseva, the shuttle service was discontinued, and the use of the ring with its platform at this station was discontinued, although both were retained for emergency use.
Geographically, the station is located in a rather exotic location: the most nearby street with automobile traffic is about 15-minute walk via a private housing sector. Moreover, the station only 200 metres away from a slime settling reservoir (the track of the tram pass along its dam). Nearby is a railroad station Mudryonaya, which only serves suburban trains to Piatykhatky. Which means that the station has the lowest passenger traffic in the system.
Constructively, the station is just as unique as its geographic location, as it is located on the portal of the prolonged tunnel that passes under the city centre, as a result its rotunda vestibule is located on the upper level (on top of the portal) and passengers have to descend onto the platforms, which are also located on ground level. The station presents a long stretched concrete vault with a row of supports and two side platforms. There is a series of glazed crowns that provide natural lighting at daytime and additional natural lighting comes from the glazed openings at the base of the vault between the supports.
