High-speed line Győr – Székesfehérvár – Szekszárd

This proposal would create a new high-speed route from Wien (Vienna) to Beograd (Belgrade), by-passing Budapest. It assumes construction of a high-speed line (HSL) between Wien and Győr, which is not described further here. It is also conditional on the earlier proposal for a high-speed line Budapest – Szekszárd – Novi Sad. The HSL from Győr via Székesfehérvár, would join that line near Sárbogárd. Trains would continue to Szekszárd, Baja, Sombor, Novi Sad and Beograd (Belgrade).

The line would use a natural route through the Transdanubian central range: the Mór graben or Móri-árok. This trench is a tectonic feature, and subject to earthquakes: it lies between the Bakony and Vértes hills. It is aligned north-west to south-east, almost on a line between Győr and Székesfehérvár. National road 81 runs through the valley, and rail line 5, which begins at Komárom. However, these are not main transit routes (which are centred on Budapest). The only intermediate towns are Mór (population 14 500) and Kisbér (7 500). Line 5 was closed in the 2009 round of rail closures, but that closure has now been reversed.

Győr has a population of 129 000. It is on the southern rail route from Wien to Budapest, half-way between the two. (This is Hungarian line 1). Trains would exit the station along this (upgraded) line, as far as the minimal station Győr-Gyárváros. The new line would then diverge, turning south-east through an undeveloped area, roughly parallel to highway 81. The new line would cross the motorway M1, and then continue for about 30 km to Kisbér. At first the land is flat (130 m altitude), but about 10 km from Kisbér the line would begin to climb to 200 m. The line might be used by a fast regional service (which would use the existing line after Kisbér).

The new section would join line 5 at the south end of Kisbér, about 2 km from the station. This point is 39 km from Győr station. (For regional trains, there would be a link to the station). From Kisbér to Mór (about 20 km), the new line would closely follow the old, but the curvature must be improved.

From Mór, the new line can follow line 5, in an almost straight line to the outskirts of Székesfehérvár. There, it curves east, and joins the lines from Lake Balaton and Veszprém, about 1200 m west of the main station. (The curve has a radius of about 1000 m, which is acceptable since all trains will stop). The line from the junction at Kisbér would be about 46 km long, giving a total of 85 km from Győr. Székesfehérvár is a railway junction, although the dominant axis is clearly the Budapest – Lake Balaton – Nagykanizsa – Ljubljana line. The historic city has a population of 102 000, and is the regional centre of Central Transdanubia.

To exit the station, trains would use the Budapest line, which turns south-east at first. The next section of new line would diverge from this section, and then turn toward highway 63 (toward Sárbogárd). South of Belsőbáránd, it would follow the local line 45 to Sárbogárd. This section (shown in red) would be about 35 km long. At Sárbogárd, the new line would join the HSL Budapest – Szekszárd – Novi Sad (shown in blue). (South of Sárbogárd, that HSL would follow line 46, along the Sárvíz valley, toward Szekszárd).

The line from Székesfehérvár to Szekszárd would be about 100 km long. Total line length from Győr to Szekszárd would be 185 km, of which 65 km are shared with another HSL route. Because the line follows tectonic and river valleys, it can be aligned for high speeds (300 km/h). A one-hour journey from Győr to Szekszárd is feasible, even with one stop at Székesfehérvár. That would dramatically improve inter-regional rail services, as well as providing a new European high-speed route.
