The Bavarian Eastern Railway Company gained the concession to build the line was on 3 January 1862. Construction began later that year and was completed on 1 December 1863. From Schwandorf station to Irrenlohe station its single track ran parallel with the also single-track Regensburg–Schwandorf–Amberg–Nuremberg line of the Eastern Railway. It ended in its own station in Bayreuth south of the former Brandenburger Thor, which had a roundhouse, a goods shed, a carriage shed and a residential block for railway officials. To reduce costs, however, passenger traffic was handled from the beginning at the platform of the Bayreuth–Neuenmarkt-Wirsberg railway. With the commissioning of the Eastern Railway line, the former Bayreuth terminus became a through station on the Hof–Bayreuth–Weiden–Regensburg–Munich route, which at first required changes in Bayreuth and Irrenlohe. As a result, the line from Bayreuth to Munich was 40 Bavarian miles long, 12.5 miles shorter than via Augsburg. Train crossings were scheduled at Parkstein-Hütten, Kemnath-Neustadt, Kirchenlaibach and Seybothenreuth. Initially, three pairs of passenger trains operated between Bayreuth and Irrenlohe. In international traffic, a passenger train running without changing carriages between Cologne and Vienna was added in the 1860s. On 1 January 1876, the Bavarian Eastern Railway Company was nationalised and the line was taken over by the Royal Bavarian State Railways. The two Bayreuth stations were merged at the same time, requiring a change to the track layout. The Schwandorf–Weiden section is now considered to be part of the Regensburg–Weiden railway.
Route
The line branches from the Regensburg–Weiden railway at Weiden station and proceeds along the B 470 highway through the Weiden suburbs of Rehbühl and Weiden-West and past the Seltmann porcelain factory. Near the Brandweiher estate the route swings to the southwest and then runs northwest through the Manteler forest and from Schwarzenbach along the Haidenaab to Pressath. In Pressath a branch line to Kirchenthumbach branched off until 1962 and there is still a siding to the Grafenwöhr training camp. Next, the line runs along the Haidenaab, passing to the east side of Rauher Kulm and meets the Nuremberg–Cheb railway at Kirchenlaibach station. After Kirchenlaibach station the line runs to the northwest along the B 22 through the Seybothenreuth forest and between the Pensenberg and Schlehenberg mountains to Bayreuth. The line passes through the Bayreuth districts of Grunau, Colmdorf and Neue Heimat and then reaches the line from Schnabelwaid. The two lines run parallel across the valley of the Red Main river on a nearly 1.5 km long embankment; the line from Weiden runs on the eastern track. Coming from the south the two lines cross the B 22, then the Bayreuth mill canal and finally, just before the entrance to Bayreuth station, it crosses the B 2 and immediately afterwards the Red Main.
Track standard
The route is single track over its entire length and not electrified.
