what is a line?, phone footage of travel

I was on the train from Letchworth to Leeds and I thought of line definitions, one being 'series of events', this could relate to repetition of trees, houses and whatever else I past on the way up to Leeds. I also saw travel as a line, its the distance and the route taken up to a certain place. I just filmed short amounts of time of what I saw, I kept the window frame in the same place as a way to hint obviously, line. In a way they are short diaries of what I saw, what may just seem as a blur, this communicates the speed of the train and the journey I took.
