The wooden pony wagons were usually enclosed, but the roof was removed, and the sides were reinforced metal plates. The wheels were also reinforced and, while normally attached directly underneath the body, were connected to what looked like some sort of bent metal that raised the body slightly higher. The front of the wagons had a metallic structure which looked like an emplacement of some kind, along with a curved metal shield. Underneath that was a small dip, like a bucket.
