Not in the best quality, but here's one:
EDIT: And I do think the ride suffers (a little) without the dueling feature. There's a couple close calls you no longer get without two trains on the track. Montu's track layout is a better example of the same ride system utilized with only one train in mind. Dragons was intended for two and it shows in a couple places. There's still some great stuff on the ride, but I understand why some are disappointed in it not dueling.
