At the end of hours of train-dreaming, we may feel we have been returned to ourselves - that is, brought back into contact with emotions and ideas of importance to us. It is not necessarily at home that we best encounter our true selves. The furniture insists that we cannot change because it does not; the domestice setting keeps us tethered to the person we are in ordinary life, but who may not be who we essentially are.

If we find poetry in the service station and motel, if we are drawn to the airport or train carriage, it is perhaps because, in spite of their architectural compromises and discomforts, in spite of their garish colours and harsh lighting, we implicitly feel that these isolated places offer us a material setting for an alternative to the selfish ease, the habits and confinement of the ordinary, rooted world.
