Almost penniless and no idea where I am in London, but taking various tube trains to attempt to get back to somewhere familiar. At some stage I am hanging around a busy station when I am taken for an employee by a Transport for London worker, who hands me a plastic tube with attached funnel. This is for distributing tea to the the rest of the staff; he also gives me a demijohn full of milky-looking tea.
At this point, I am distracted by a large flat-bed wagon passing the platform. Sitting on it are a variety of railway workers, some lounging, some sitting on crates and reading newspapers. Helpfully, the battered and well-used wagon has the words 'trainless drivers' painted on its side.
