The railcar type U is the first vehicle generation of the Vienna subway. It was produced from 1972 and runs on all lines except for the U6 line.
In 1978, the type U1 and U11 were introduced. These are almost identical in appearance to the original vehicles.
Since 2000, the successor generation, the Type V, has been in production.
