No person shall molest or wilfully interfere with the comfort or convenience of any person on the railway.

Any person directed by a notice to queue, or when asked to queue by an authorised person, shall join the rear of the queue and obey the reasonable instructions of any authorised person regulating the queue
Who can find an image of a "queue here" sign?
