The Acela bathrooms have windows, but they have that opaque coating so no one can see in but light is let through. Superliner I Sleepers have a window in the upstairs restroom, but there is a curtain. Viewliner Standard bedroom has the toilet with those huge windows, but again, with curtains.
No I do not want anyone looking at me while I'm in he restroom thankyou very much. <_<
