A lupwI' thing which transports is a jitney, a people-transporter. A lupDujHom is a shuttlecraft. A train is a lupwI' mIr and a taxi is a ra'wI' lupwI'. All of these suggest lup refers to passengers rather than cargo. If someone wants to equate passengers with cargo, that's their own lookout.
I have seen the word "deliver" used in the context of public transit ("The train delivered the passengers to their destination.") However, having checked a few dictionaries and other sources, I see that it is a usage used more by lawyers while discussing contracts of transport than in everyday speech. :-)
