TOFC Facility

I have been working on an early TOFC facility and it's beginning to look like something. I purchased the Britkits Early TOFC sets and they are perfect for my time period. I did, however run into one snag. I know how to load and unload the cars, but is there a way to place some of the trailers on the ground so they look like they are ready for pickup or ready for loading onto the flatcars?
