4313 is seen closer to Zentralfriedhof 3. Tor with, in the foreground, one of the tram stops with white stripes on the pole which are seen in a few places on the network. These are not regular stopping points but provide somewhere to load and unload for irregular workings. In this instance it is likely that it would have been used when special trams ran to and from Zentralfriedhof to allow several to load or unload at the same time. In Vienna trams are only allowed to load and unload at designated stops so additional ones have to be provided where unusual levels of traffic can be occasionally expected.
