The ÖBB 1064 008-4 at Wien Zentralverschiebebahnhof Kledering

We passed through the marshalling yard to get on the Duna-bridge to Stadlau and then on to Strasshof. At Süssenbrunn we passed through a great union style junction between two double-track railways crossing on two levels with coverleaf tracks allowing trains to go from any direction to any of the other directions. Just like a motorway-junction.
