On February 7, 2021, snow storm Darcy caused the shutdown of the entire Amsterdam tram system. By February 9, tram lines 5 and 17 were again in operation. However, by February 10, lines 1, 3, 4, 13, 14, 24 and 25 were still not operating. It took three days to clear ice and snow on all tram lines, the problem being aggravated by road traffic pushing snow back on the rails and refreezing. To help with clearing the rails, the GVB borrowed two preserved work cars and crew from the Electrische Museumtramlijn Amsterdam, a local operating tram museum. One vintage car used was a snow scraper originally from the Wiener Linien (Vienna). A second museum car was a former streetcar modified to carry a tank to sprinkle brine onto the tracks. The two cars were operated by museum staff.
