The preparations

As the Wien-Raaber Bahn reached the feet of the Semmering pass and later on, as the pass railway (the world's first-ever mountain railway) was developed, the flourishing, wet, lumber-heavy valleys in the area attracted loads of investors. Neusiedler AG wanted to build a paper mill along the Schwarza river to exploit the dense pinewood forests of the area and therefore the planning of a standard-gauge railway from Südbahn's Payerbach-Reichenau station to Hirschwang (the village at the feet of the Raxalpe, to house the paper mill) and a branch to Prien, both electrified by DC, was started.

Narrow-gauge train to Cortina d'Ampezzo

Using the groundworks of the 70 cm Austrian military railway and utilising the reparations paid by World War losing Austria to Italy, Ferrovia della Dolomiti, a 950 mm/95 cm gauge narrow-gauge railway had been built of a total length of 65 km from Toblach in South-Tyrol through Cortina d'Ampezzo to Calalzo, where connection to the Italian mainlines was provided. The railway line was opened for civil travel in 1921 and electrification was finished by 1929 with 2700 V direct current.

The Austrian Federal Railways (ÖBB) had electrified many railway lines at the very early days of mainline electrification choosing the then most-advanced low-frequency alternating current system with 15 kV, 16 (2/3) Hz AC voltage. The federal capital Wien was reached by electric trains in 1952 as the main area for electrification had been the mountain passes. In those years Austria was still under Allied occupation with the capital being inside the zone controlled by the Soviet Union but the city itself split up into four control zones very similarly to those of Berlin. But while Berlin and Germany gradually shifted into an Eastern and Western part Austria was jointly run by the four allies and in 1955 given independence.
After that, the development of the city sped up and required the establishment of a commuter railway network which later incorporated various rail links inside the city and became the Vienna S-Bahn. The main vehicle on the S-Bahn became the ÖBB class 4030 electric multiple unit which had almost the same features as the subject of the present article, only being different in exterior design and the electric systems.
