If a bubble cement is going to be produced it should be the complete wagon. Correct chassis, body, ladders walkways, underframe equipment discharge units brake gear, buffers etc. I think it is the one area of the the hobby that is in need of being brought into the mainstream. As a modeler I am more attracted to the freight side of the prototype. The bubbles can have three liveries, weathered versions of the three, single packs, three packs. I'd shell out 200 notes for eight rtr bubbles or beets as opposed to a loco. Can you imagine a wagon to the standard of the GM's.
