After creating a train with items, closing, and sending, receiving the items back is confusing. The table allows you to select an individual item but it is not clear what, if anything, happens. An item can be selected but the only option is to close the train once selected. It appears that a "train" can be received, but not individual items within the train. It would be nice to be able to receive individual items within a train.

Much of this depends on the processing and workflow created. I can see groups of items being sent and individual items being received back one at a time.
