of Fürth had threatened a complaint against the plan. It refused to approval the relocation of the S-Bahn and demanded that the S-Bahn be bundled with the existing line. PFA 17 ("Erlangen"): The planning approval decision was issued in November 2009; the construction started in November 2011. PFA 18/19 (Forchheim/Eggolsheim): the planning approval process had been discontinued in 1996 and 1997, but the planning approval process resumed 2013. Planning approval for the 14 km-long section was given in January 2016. The planning approval procedure was presented in April 1996 and the report of the hearing was presented in November 1996 and the procedure was suspended for the planning phase section 23/24, from the northern town limits of Bamberg to the northern edge of Marktes Zapfendorf. It was continued between 2013 and 2015 with three changes in planning procedures and concluded by an approval on 30 July 2015. Construction work in section between Breitengüßbach (km 68.9+73) and Zapfendorf (km 77.7+07) began in 2015 and is due to be completed in late 2017 (status: February 2014). The corresponding building contract was awarded to Leonhardt Weiss & Co. KG in October 2015 for €145 million. The mainline was completely blockaded from 11 January to 4 September 2016. The cost of the substitute buses was about €3.5 million. The planning approval process also applied to changes at Nuremberg Hauptbahnhof. A total of 220 kilometres tracks with 250 sets of points and 160 bridges are to be built or rebuilt. At 26 railway stations, platforms are to be replaced or adapted, 25 level crossings are to be closed and largely replaced by new overpasses and/or underpasses. Eleven level crossings had been eliminated by June 2007, and the planning or planning approval procedure had been initiated for nine level crossings. The environmental measures on the upgraded line include measures to increase biodiversity in the Fürther Rednitzgrund (between Stadeln and Vach) and the provision of financial resources to the city of Erlangen for measures to develop water courses. At the beginning of 1997, an upgrade for services up to 200 km/h was proposed. There would also be several overtaking loops. Construction In advance of the main projects, four bridges and the railway power supply have been renewed since 1996 in the area of the upgrade. Between 1998 and 2006, two substations were established. Work began on the provision of four tracks between Nuremberg and Fürth in 2006.
