Schaffnerlos sign means that there is no person inside of the car/carriage. If you're a weeb, you might've seen the sign ワンマン (one man) on trains in Japan, which means one-man operation. It's the same thing basically. The difference is that in Vienna all of the trams and buses are now Schaffnerlos and nobody puts the sign now, but in Japan ワンマン sign still sometimes appears.
