The electric units in the 1950s and 1960s were used by most working folk, as well as university students, living in the suburbs. Such was the demand for rail transport that most carriages were full to 'standing room only' in the morning and again in the evening. Reading the Dominion or Evening Post was a challenge in such cramped conditions. As a university student I watched and learned how it was done. One could read the entire newspaper, regardless of the number of pages or how it was divided up, without moving ones arms past the invisible centre line of the seat. It was an amazing art of origami, but often silently scoffed at by those who read books or other academic literature.
