Fred, just click under download, then choose different size of containers. Tim, looking forward to new items from TNT-Z. One question. Could the trailers be made so that it can be used for the well cars and flat cars by simply not attaching the wheels, or is it simply the case where they are just too different? I would like a little variety on the shape of the containers. I guess no matter how tired I am, I always find running trains to be very relaxing, especially when all the when all the wheels are metal. Clik, Click, Clik, Click.
