Zagreb–Belgrade railway

The Zagreb–Belgrade railway (Pruga Zagreb-Beograd) was the Yugoslav Railways′ 412 km long railway line connecting the cities of Zagreb and Belgrade in SR Croatia and SR Serbia, at the time of Yugoslavia.

It was the route of the Orient Express service from 1919 to 1977.

Electrification was finished in 1970. It was the first fully electrified line in Croatia with a 25 kV 50 AC system (Zagreb-Rijeka was electrified earlier, but with an older 3 kV DC system).

Since the breakup of Yugoslavia, it was split into the Zagreb-Tovarnik railway and the Belgrade–Šid railway, operated by Croatian Railways and Serbian Railways, respectively.
