The Eurovision semi-finals are being held in Vienna’s Stadthalle on May 19th and 21st and the final takes place on May 23rd.
Bearded drag queen Wurst won the Eurovision Song Contest for Austria in May last year.
"Conchita Wurst will record announcements for trains and stations, in German, English and French," Wiener Linien transport spokesman Answer Lang told Austrian broadcaster ORF.
Lang said he could not yet give details as to what exactly Wurst would say. “The announcements will be concentrated particularly on public transport around Song Contest locations,” he added. They will be broadcast during the Song Contest week, and maybe earlier.
Vienna looks set to temporarily rebrand itself in May, with the slogan "City of Vienna - # 12 points" appearing on posters and billboards around the capital. It refers to the maximum number of points possible in the competition.
Alexander Wrabetz, director of Austrian broadcaster ORF, said everything will be done to ensure Vienna scores top points as a host city.
