I noticed some passenger car sets offer a dome car and there is also a full length dome car add-on available. Of course they do the same with Pennsy sets and Pennsy didn't (couldn't) run them do to the height requirements.
Also, did NH have names for their various passenger schemes? I know of two streamliner schemes, the Pullman 86OO (orange window band) and there was a predominately black with top orange band.
Thanks,
