I just received my lasted issue of NSR and under Trainworx I see the announcement for a bulk liquid trailer. This is how the announcement reads.....Up soon should see an all-new N scale bulk liquid trailer. The prototype carries water, milk, asphalt and similar commodities....but not at the same time. I just hope that Trainworx over makes this product to allow everyone who needs them to get a few this could be an interesting model and could set the stage for more trailers and maybe someone will do structures to support new industries. One could hope....
