Instructions for participants The event took as a starting point the Hitchcock film 'Strangers on a Train', which is about two people 'swapping' murders in order to avoid detection. There are lots of visual allusions to the concept of pairs of things in the film: the tennis crowd following the ball from one side of the court to the other, the contrast of the personalities of the two lead men, the contrast of their shoes at the start, etc.; and then there's the visual props - the cigarette lighter, the carousel, the spectacles. So dualism, pairing, opposites, exchange, split personalities etc. were the basic ideas of the event. Artists were invited to produce a work in any medium which engaged with the theme of the project. For the outward journey: Each artist made their way (with their artwork) to the agreed railway station and to the platform where the train from London to Newcastle arrived. When the train arrived, each artist went to the pre-arranged door of the train, and exchanged their artwork with that of an artist onboard (who was waiting at the same door). The artist onboard was in possession of a work by an artist from the preceding station. Each artist then had two days to make alterations/additions/amendments to the work they had received, bearing in mind the theme of the project. For the return journey: Each artist made their way, with the work they have altered, back to the agreed railway station and to the platform where the train from Newcastle to London was due to arrive. When the train arrived, each artist went to the pre-arranged door of the train, and returned the work to an artist onboard (who was waiting at the same door), in exchange for their own original work. The work given to the artist onboard was then returned to its owner at the next station.
