Where I can find more info about this?

Well, this bus is tehnicly an "reserv" bus, so from time to time, it will be used on routes. Lately this bus was taken out on these routes, for fun, but I don't know, how long it will last. There is no real easy way of knowing, but I can tell, that it will most likely be on the 3.department routes.
