Turgi and Koblenz on 14 October 1944. The section between Koblenz and Waldshut, however, was electrified in 1999. Special features of the Koblenz–Waldshut line The property boundary between the Swiss Northeastern Railway (now part of Swiss Federal Railways Infrastructure) and the Grand Duchy of Baden State Railway (now part of DB Netze) was in the middle of the Waldshut–Koblenz Rhine Bridge, which the national border between Switzerland and Baden. The two participating companies each built their half of the bridge. The northern part of the bridge and the northern abutment are owned and are the responsibility of the German company, while the southern part and the southern abutment are owned by the Swiss company. This ownership is unusual, because the property boundaries of railways usually are immediately next to stations or service depots, but not in the middle of a line. Route Immediately after Turgi station the line turns in a sharp curve to the north and cross a three span stone bridge over the Limmat. It then runs over an embankment and a cutting. Between Siggenthal-Würenlingen and Döttingen stations it includes a roughly five kilometre long, straight section that is not common in Switzerland. The distance of 6.6 kilometres between the two station is relatively long. On this stretch there are two sidings connecting to ZWILAG (an interim nuclear waste storage facility) and the Beznau Nuclear Power Plant. Döttingen station was called Döttingen Klingnau between 1897 and 2002, when the second half of the name was dropped, with the opening of Klingnau station. Between Döttigen and Klingau the line runs along the natural terrain. The line's curve into Koblenz is very sharp and only allows a speed of 40 km/h. The Turgi–Koblenz section has a weight limit of 22.5 tons per axle and 8 tons per metre and thus the line is approved for class D4 traffic. After leaving the station in Koblenz, the line through a deep cutting through the Frittel Hill and climbs a 1.2% grade to the curved Koblenz Tunnel. The line runs over an embankment and a viaduct through the middle of the town of Koblenz, crossing the Winterthur–Bülach–Koblenz railway line and, about 150 metres later, the main road. The line then runs over one of the oldest railway bridges in Europe, the bridge across the Rhine, the Waldshut–Koblenz Rhine Bridge. The northern embankment continues to Waldshut station.
