The most direct option is to go to the petrol stations to on the motorway by train and then foot. If you take the S6 (to Wurenlos) or the S12 (to Kilwangen-Spreitenbach), you will be near the petrol stations. There is plenty of international traffic here. I also know that one can use this petrol station to go east and south of Zurich by using the opposite side of the petrol station.
