. A whiff of smoke, a sudden spark or the smell of ozone always told you that it was probably too late to save whatever it was that had gone south. I think running trains is one of the few times any of these things are acceptable, and sometimes desirable.

Yeah, good point. For years, people have been touting the wonders of DCC. First there was motion and selection, next came sound. Now we have DCC smell. Almost wants to make me switch.
