Now, the two parallel lines run through Pöchlarn station until the new line takes a slight curve to the left to enter the almost 5 km long Sittenberg Tunnel. Shortly after the western portal the new and old lines come together again and, about 2 km later, reach Ybbs an der Donau station, where the maximum speed is cut to 160 km/h. The two-track line section between Ybbs and Amstetten is expected to be rebuilt as four tracks by 2016. Amstetten–Linz Kleinmünchen From Amstetten station, the Western Railway runs as four tracks again and with the recommencement of LZB long-distance traffic can accelerate to 200 km/h after the sharp left turn at the western exit to the station, which restricts speeds to 160 km/h. The Old and New Western Railways run parallel as far as St. Peter-Seitenstetten, before the new line makes a tighter curve than the existing route through the St. Peter “green” tunnel. At St. Johann-Weistrach the two lines run for a few hundred meters next to each other again. After the station, the Old Western Railway runs towards Haag, while the New Western Railway takes a right turn to a straight section and then runs to the north through the 6.5 km long Sieberg Tunnel. At the northern portal, the two lines meet and again run parallel to each other to St. Valentin station. After the station, the new line enters the “Enns bypass”, which can be operated at 230 km/h, running around the area of the port and the settled areas of Enns. (In 2005, in the course of the upgrade to four tracks between Ennsdorf and Enns, a junction was built towards Mauthausen, allowing direct operations of trains from Linz towards the Danube Bank Railway). Near Asten, the Old and New Western Railways come together again. From Asten-Fisching 1 junction the speed limit is reduced to 200 km/h on the two parallel lines to Linz Kleinmünchen, the current end of the four-track section on the Western Railway. Signalling The New Western Railway has been equipped with the European Train Control System (ETCS) on the newly built section of the line from Vienna to Wagram junction. The so-called “registration” (Anmelde) line starts at the entrance to Lainz Tunnel, which is equipped with both ETCS and with the old Punktförmige Zugbeeinflussung (PZB) system. From Hadersdorf junction it was originally intended that the line be exclusively signalled with
