The 76cm gauge railways of Yugoslavia

Uskotracne (76-centimetarske) pruge bivse Jugoslavije


Mokra Gora and the Sargan 8

At the end of the First World War, the 57 Km stretch between Uzice and Vardiste was the main missing link in a continuous 76 cm railway between the state capital Belgrade and the Bosnian capital Sarajevo.   Its construction became a priority for the new state of Yugoslavia.  The most difficult task was how to build a railway over the Sargan mountain which did not need a rack section or excessive gradients.  The map below illustrates how it was done:

Construction began on March 1st 1921 and, despite many setbacks, the section opened on 2nd February 1925.  The final 40 Km missing link between Belgrade and Obrenovac opened on 30th October 1928 and a through 76 cm railway now existed over the 444 Km from Belgrade to Sarajevo.

The climb over the Sargan Mountain was an engineering masterpiece.  From Uzice to the summit the height difference was 240 metres.  As the crow flies it was 3.5 Km but by rail it was 15.4 Km.  The average gradient was 18% (1 in 55) and there were 20 tunnels including the summit tunnel of 1,666m.

Just short of 50 years later, on February 28th 1974, the last train ran over the Sargan Mountain.  Fortunately the line between Mokra Gora and the top of Sargan Mountain has been revived, this is now the only section of the once great Yugoslav 760mm system to be preserved as a living railway.  Trains currently run between Sargan Vitasi and Mokra Gora (Serbia). An extension to Visegrad in Bosnia was completed in 2010 but there does'nt yet appear to be a regular service.

More about this project can be found on the Serbian Railways website  

Thanks to Milan Suvajac for the use of the maps.

  Steam trains are presently hauled by Class 83 No. 83-052 (Jung 3534/1923) and 83-173 (DD 129/1949).  It is also planned to restore 85-045 (SlBr 32/1940) and possibly other locos for use on the line in the future.  When the extension to Visegrad is fully open the preserved section of railway will be 43Km (26.7 miles) long.
