December 1, 2016. Canal Street. The new (1997-2003) Canal Street cars are air conditioned, and the ducting for the air conditioning created what I call rabbit ears on the roof. It looks rather unattractive and unhistoric to me, and I would have thought if they were spending the money to create traditional looking streetcars that they could have designed the AC ducts be less intrusive, or perhaps look more like a real clerestory roof.
