Neckar-Alb line gets bidirectional track operation Nürtingen–Reutlingen

The double-track section of the Neckar-Alb-Bahn (Plochingen–Tübingen railway) between Nürtingen (km 12.4) and Reutlingen Hbf (km 34.7) was equipped with bidirectional track operation (Gleiswechselbetrieb, GWB), allowing both tracks to be used in either direction so train service can continue even when one track is closed for maintenance or disruptions, and faster trains can overtake slower ones. The first construction phase (April 2015 to March 2016) included 26 new signal foundations, 26 signals, 9 insulated joints and 2 provisional crossings; a second phase with additional cable-duct work was planned for 2018. According to Wikipedia, the upgrade is linked to integrating the new Wendlingen–Ulm high-speed line (Stuttgart 21) into the existing line.
