Sorry, it's a BAe 146, and those have long gone in Crossair, they use the Avro RJs (I admit, the difference is little).
Swiss will never buy EMB175/190 because they don't have the money, LH City line also has Avro's (they even intend to buy more) and because Swissair-guys avoid flying a "regional" aircraft by all means, they wouldn't have those fancy Airbus ratings (with the link to the wide bodies) anymore.
