Drum, but not the sort you play on: one of the large drainage pipes or flues used as culverts, named in 1922 after the local kuivenduskraavi trummi or drainage ditch ‘drum’ aka truup:truubi, culvert. Why Trummi was chosen instead of Truubi is unclear. Once also known (dates unsure) as Brückenstraße (bridge st) or Мостовая ул. (pavement / bridge st) shedding further light: while мостовая originally meant ‘street paved with round logs’, and derives from ‘bridge’, it seems to indicate the engineering consequence of covering a watercourse to make it easily passable. But see Truubi. Parent street-name of a now hydrology-themed sector.
1) Firebrand (cf. Icelandic and Old Norse tungl, moon); 2) Smut, blight, rust (plant mold or fungus). But neither one nor the other. Originally Sõpruse (1952-58), street renamed some 30 years after the Taara and Vanemuise group surrounding it, and a search in Kalevipoeg reveals it to be a mythical kingdom whose son and heir comes to press his suit on Linda but, like his four predecessors, gets taken to the cleaners. Also a well-known song by Kuhlbarsi F. and Hermanni K.A., Kungla rahvas (people of Kungla). Derived from Swedish kungliga (royal, kingly) and thought to be calqued on Gotland.
