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 Following problems with capacity of the A cars which are small for what is a very busy route, they have been replaced by B class ULF cars and also the more recent B1 class. At the end of 2012 E2 trams with c5 trailers were introduced and have replaced the E1 trams.
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.
