   • 2012, Andrew Martin, Underground Overground: A passenger's history of the Tube, Profile Books, →ISBN, page 277:

     The new trains will also be fully 'walk-through', with no carriage end-doors. Travelling on them is like riding on a sinuous, moving corridor. It's less claustrophobic than the old arrangement, but now you can no longer choose the carriage not occupied by the declaiming loony.
