I was wondering the other day if anyone has made some air hoses that really attach between cars? It seems like it would not be that hard but I haven't seen any manufacturers do this so maybe it is harder than I'm thinking or not worth the effort? For folks that have automated coupling/uncoupling I image this would be difficult and not even desireable. But when I hook up a train and run it I usually run it for a while. For close up pics of a train it looks strange for the air hoses not to be connected.
