Thank you for the video, Tourcoach, has a alot of these ex-OCTA Phantoms. I even remember in the early, when they still had their Cummins L-10, and those engine roared. I love the Series 50, because of it's one of a kind sound that it only share with it larger sister, the Series 60.
we have a handful of 1999 Orion V buses left with the DD50 engines in them but they are being retired at the end of this year through early 2018. Im gonna miss them. Most of the fleet was retired in 2010 when our other buses came along
