FRANKFURT, April 11 (Reuters) - German industrial conglomerate Siemens SIEGn.DE and Canada's Bombardier BBDb.TO are in advanced talks to combine their train operations in a joint venture, a source close to the matter told Reuters on Tuesday.
Siemens and Bombardier declined to comment on the news, which was earlier reported by Bloomberg.
The deal, which Bloomberg said could come by the middle of the year, would require clearance from antitrust authorities and face potential opposition from unions.
