A new London bus route 22 found under Décor / Misc. Decor, costs 0. I've added a driver compartment made mostly of glass, a driver's glass door, a ticket machine, money tray and 2 ramps, at the entrance and exit. All the windows have a dark tint.
NB. The number plates of bus route 74 and this one are taken from real London buses.
