The Rhine Valley is one of the most important transport corridors in Germany. There are two main railway lines, one at the left side of the river (Linke Rheinstrecke) and other at the right side of the river (Rechte Rheinstrecke). The West Rhine railway is a famously picturesque, double-track electrified railway line running for 185km from Cologne via Bonn, Koblenz, and Bingen to Mainz. It is situated close to the western (left) bank of the river Rhine. The East Rhine Railway is a major, double-track, electrified railway line, running along the right bank of the Rhine from Cologne to Wiesbaden. The 179km long line forms two Deutsche Bahn routes. Route 465 extends from Cologne to Koblenz, via Troisdorf, Bonn-Beuel, Unkel, and Neuwied. Route 466 extends to Wiesbaden, via Rüdesheim am Rhein. Together with the Taunus railway (Route 645.1), the line is used by Stadt-Express line SE-10 of the Rhine-Main Transport Association, which runs from Frankfurt to Koblenz and Neuwied. With the Cologne-Frankfurt high-speed railway and the Sieg Railway, the East Rhine Railway forms a six-track line between Cologne-Porz and Troisdorf. It includes two tunnels between Rüdesheim and Niederlahnstein, including the well-known Loreley Tunnel near Sankt Goarshausen.
