Waiting

Travel involves a lot of waiting. Waiting for the bus, waiting for the train, sometimes the waiting time even exceeds the travelling time, especially true when short haul air travel is involved.

The man is reading a book maybe he has a long wait.

The sign "Welcome to Aberdeen" faces towards the station entrance, and so is more obvious to those already in Aberdeen and are intending to leave, rather than to those alighting from a train arriving in Aberdeen.
