I have just returned from aholiday in Austria and whilst travelling into Vienna I briefly spotted 3 steam locos parked in a bay platform and I believe the station was Heiligen Stadt on the line into Vienna Franz Josef . One loco was a large tank no. 77 250 , the other 2 were large tender locos . One may have been 31122 . Any help in the identities of the locos and any other info would be much appreciated .
