I'm not familiar with the design you posted, so I'm not sure of era or region.
That said, there is a severe lack of "modern" intermodal equipment. For the most part fixed assets (e.g. a crane) is not used to load them anymore, it's all the loader/forklift sort of thing. N scale of nevada made the piggy packer back in the day. Someone else makes one model, but I think that is it. I don't know a lot about the equipment, but I know it's an area that is lacking.
