Eastern rail exit from Belgrade

The previous post on Belgrade as a European rail junction noted the poor quality of the railway lines south of the city. That has geographical and historical origins: mountainous terrain, and the historical isolation of the Ottoman territories in south-eastern Europe. Belgrade (Beograd) was a fortress city, built for defence, not transport. There are broad rivers to the north, and hills to the south. The three railways southwards follow winding valleys through these hills.

These hills can be avoided by a new exit line east of Belgrade, to Smederevo. From there, it can turn south along the broad valley of the Velika Morava. There is no historical precedent for this route – not surprising, since it must cross the Danube twice. The previous post did propose a northern bypass of Belgrade, running from Batajnica via Pančevo to Smederevo. Although it is intended as a bypass, it would also create a north-eastern exit from Belgrade: trains could use the existing line to Pančevo, and then the bypass to Smederevo.

Beograd north bypass

The eastern exit line proposed here, is a shorter version of that route — about 45 km long. The two projects are compatible, but the eastern exit line would allow construction of a new central station on the Danube bank, within Belgrade itself. That was not foreseen in the earlier proposals.

The new line would run north from the old main station, and turn east parallel to the Danube. East of Karaburma it would enter a long tunnel, emerging directly onto a Danube bridge. On the opposite bank it would cross flat open farmland to a new Smederevo bridge. Via an upgraded line through Smederevo, it would reach the existing junction at Mala Krsna, in the Morava Valley.

Components of the route

The proposal requires a reconstruction of the old main Station (Glavna Stanica), with underground through platforms. Reconstruction was proposed here earlier, but the earlier proposals are not consistent with an eastern exit line.

From the new platforms, trains would enter a curved tunnel under the historic city, about 2500 m long. It would emerge at the existing Beograd-Dunav station, or close to it. The line would then continue eastwards, passing under the approaches to the existing Pančevo bridge.

That would allow construction of a new station, aligned east-west, just south of the existing Pančevački most station. The station would have interchange with the regional metro BG-Voz, and regional services (Beovoz). The area is still suitable for major redevelopment, although less so as the Danube waterfront is redeveloped. The platforms of the new station will be at right angles to the line from the Pančevo bridge, as it enters the Vračar tunnel. They would probably be at a lower level, since a viaduct would conflict with the bridge approach roads.

East of this station, the line would continue to Karaburma. A connection from the Vračar tunnel toward Karaburma is already planned, and that would allow through services to the new eastern exit. This area is relatively undeveloped, although that too will inevitably change.

Karaburma-Danube tunnel

The line would then enter a tunnel, about 7-8 km long, under the ridge south of Visnjica. The exact alignment depends on local circumstances, but the shortest variant would pass under the village of Slanci. The line would emerge from tunnel south of Veliko Selo, and cross the Danube and floodplain, on a combination of viaduct and bridge.

On the opposite bank, the line would pass between Starčevo and Omoljica, and then turn to a new Danube bridge at Smederevo. That bridge was proposed here earlier as part of a Smederevo – Kovin – Vršac line, which could also function as an eastern bypass of Belgrade.

Starcevo line

The alignment of the proposed rail bridge at Smederevo is constrained by the historic riverside fort, and it can not cross the river at right angles. A bridge further east would not have that problem, but then the new Smederevo station would on the wrong side of an industrial area. In any case the new line can turn as it approaches the bridge: turning on viaduct, because it must cross an old Danube channel and a low-lying island.

The line to the Smederevo bridge could certainly be combined with the proposed northern bypass. In that case, it would probably run north of Starčevo, as shown on the diagram below. It would join the Pančevo – Smederevo line east of that village. The tunnel from Karaburma would be somewhat shorter, and the viaduct across the floodplain longer.

Starcevo combination

The floodplain here is a nature reserve, but if that is a problem, the line can also run further south, and joining the Pančevo – Smederevo line further east. In fact, it could pass south of Omoljica, but that is only marginally shorter, and it is better to allow for some form of shared alignment with the northern bypass, and also for a shared link toward Kovin.

The new line would be 44 km long, and journey time about 20 minutes. The variant alignments around Starčevo will not substantially change that. The line would be purely for through traffic: the only intermediate stop is the proposed transfer station at the Pančevo bridge. (For the villages on the northern bank, a more appropriate infrastructure is a local line from Pančevo to Kovin.)
