I doubt 5499 is on the X20 due to it being for the Hospital shuttle between the RVI and Freeman Hospital.

I have a feeling there is a driver at Deptford trolling enthusiasts by changing the fleetnumber on the ticket machine to indicate there's one of the new vehicles out. Maybe something that Dan should investigate as it's a bit unfair winding up enthusiasts and sending them on a wild goose chase for a supposed unusual vehicle for it to be a bog standard Streetlite. It has happened several times before with the White Versa, the loan Steetdeck and Streetlite and now one of the Yutongs.
