Wurger is correct, those are what I was referencing. I often wondered how the rail car mounted weapons (or the cars themselves) where stabilized. Firing a heavy cannon like that would cause quite a bit of motion to the car. Those 4 legs seem to be retractable and would stabilize the rail car when firing. Along with the retractable side platforms it is a very neat design from what I can see.
