The Original Orion 7s have the tape, the same tape seen in the Orion 5s, and then the Orion Next Gens 3800-4244 have the bars and then 4245-4278 and 4330-4702 have the tape that's flush with the door, not the tape that protrude from the door by like a few millimeters.
I kinda like the bars because they do close quickly. The vapor doors seen in the buses with the tape take forever to close. And yeah, looking at the bus roster fleet on the TTMG website there are a lot of changes that were made while the buses were being delivered.
While I'm not to fond of the Orion 7s, I'll say that the Third Gens have won me over. Speaking of the Third Gens since they relate to the BT&E fleet, I don't think we'll be getting any more Xcelsiors. They look aesthetically pleasing but at the same time, they seem cheaply made sorry to say. Someone did say that the Xcelsiors have a different body frame that's different from the D40LFRs. Wish we would've gotten those instead.
