Reply To: May one use an escalator on shabbos?

AviK: I don’t have access to R’Moshe’s teshuvo now, but this issue of “zilzul shabbos’ is -bemechilas kevod hatorah- a new invention. Certainly, this approach is not found amongst early Poskim. “Uvdo dechol” ,yes, but “zilzul Shabbos”? You can frame virtually anything as “zilzul Shabbos”. Going around in a colored shirt, or in shorts- may not be nice but is it ossur?? And why would an escalator not be “zilzul shobbos” as per your approach?? If you allow escalators and Shabbos elevators, I do not see why public transport- especially beshaas hadechak- would be ossur.
