STA own around 230 buses. The buses are numbered 1-350, so there must be rather large gaps. Specialities in the STA fleet include Ikarus 415 buses that are completely manufactured in Hungary. An additional plus is that STA seems to operate actual city center routes solely with low floored buses. On longer regional routes normal floored Carrus Fifty -models are used.
STA currently operates an even selection of regional and internal Helsinki routes and will soon start operating most Espoo routes.
