The nostalgia train number 1820 at Kossuth Square on 23.10.2021. The S-type tram was built in 1907 and renovated in 2018.
This S-type tram was produced in the Schlick-Nicholson Factory in 1907 and entered passenger service with plate number 571. Twin 37-horsepower engines made maintenance simple and fast, as in the case of malfunctioning of an engine, the other one was sufficient to power the tram. Members of the S series received plate numbers 1800-1929 in 1924. Until the end of the BSzKRt era, the predecessor of the Budapest Transport Company (BKV), only minor changes were made on the motorcar: a manual signal-light was mounted, while the inwards-opening doors were replaced with collapsible “Hűvös-Tóbiás-system” doors, and the seat layout was modified. In the 1950s, it ran as twin-car 1714-1715, and then left passenger service only in the 1970s; thereafter it operated as a vintage twin-car in 1982. The tram was renovated in 2018 for the 50th anniversary of BKV with the usual livery of the BSzKRt era and it got back its plate number of 1820.
