The train cabride through the Belgrade railway junction has always been interesting. Basically it is passing through many tunnels, many faulty track signals and bad and good tracks. On this section of the railway, from Belgrade to Mladenovac, the train passes through the old, in some places very bad track infrastructure and through overhauled sections of the railway. Regardless of the fact that this is a very short train journey, very interesting situations happened along the way.

The 3 most interesting events in this video are:
0:18:40 Home station signal in Resnik, that shows completely unusual and unclear signal signs;
1:43:15 Faulty track signal near Ralja, that stops the passing train because it has defective track balise;
2:05:26 Faulty exit signal at Ripanj train sation, that stops the passing train because it has defective track balise and train automatic stop device failure.

The most prominent infrastructure objects along the railway:
0:03:20 Tunnel "Dedinje" (L=3086m);
0:17:44 Tunnel "Kijevo II" (L=11m);
0:45:25 Bridge near Ripanj Tunel station;
0:47:52 Tunnel "Ripanj tunel" (L=1614m);
0:53:48 Bridge "Parcani" (L=186m);
0:55:30 Tunnel "Parcani" (L=230m);
0:57:12 Station Ralja (The highest point of Beograd Nis railway line, altitude 225m);
0:59:18 Tunnel "Ralja" (L=558m) (The narrowest railway tunnel at Serbian Railways);
1:17:20 Station Mladenovac (Terminus station for this Beograd suburban train);

1:18:14 Starting the return trip from Mladenovac to Beograd Centar;
1:37:50 Tunnel "Ralja" (L=558m);
1:38:40 Station Ralja;
1:41:48 Tunnel "Parcani" (L=230m) and an old German World War II bunker;
1:43:20 Bridge "Parcani" (L=186m) and an old German World War II bunker;
1:46:54 Tunnel "Ripanj tunel" (L=1614m);
2:08:00 Railroad crossing and track signaling devices are failure;
2:32:10 Tunnel "Dedinje" (L=3086m);

Along the railway, next to the old bridges and tunnels there are old German bunkers from World War II. The bunkers were used during the war for guarding important railway objects. Most of these bunkers are along the old route of the Belgrade Nis railway line, which is still the most important transport route and one of the most important railway lines in Serbia.

The recording was done from trains 7903 (Beograd Centar Mladenovac) and 7904 (Mladenovac Beograd Centar). It is a local passenger EMU train set, ZS series 412/416.
