Irving Oil once made extensive use of rail service to deliver petroleum from the Saint John refinery to rail-side distribution terminals throughout Atlantic Canada and Quebec. The decline in rural branch rail lines operated by Canadian National Railway and CP Rail in the 1980s and 1990s, combined with the increase of 4-lane highway construction, has seen Irving Oil eliminate practically all retail petroleum delivery by rail and the closure of many of its rail-side distribution terminals in favour of newer highway-served terminals or direct deliveries.
