The present 1 route was formed on 26th October 2008 from the part of the former N route and the whole of the 65 route, together with the link around the ring which had been the older 1 route.
It was worked by the depots at Währinger Gürtel and Favoriten using the shorter A class ULF cars, together with E1 trams hauling c3 or c4 trailers. Following problems with capacity of the A cars which are small for what is a very busy route, they have been replaced by B class ULF cars and also the more recent B1 class.
The service can be affected by events taking place on the Ring, particularly at weekends, and as a consequence often has to be worked as two parts.
