Legend from Eltersdorf 0.000 Weißenbrunn am Forst to Leipzig Hbf 0.407 Füllbach tunnel (1112 m) Leipzig Hbf – Eltersdorf 1.519 1.800 EÜ Füllbach (90 m) 2.100 EÜ Bundesstrasse 303 (106.5 m) 2.562 from Lichtenfels Creidlitz to Eisenach Swell:

The Niederfüllbach connection curve (also called Coburg Süd connection curve ) is a 2.5 km long, single-track railway line of the German Unity Transport Project No. 8 near the Bavarian city of Coburg . It is located in the area of ​​the community Niederfüllbach , whose name it bears, and the Lichtenfels district of Buch am Forst .

The connecting curve connects the Eisenach – Lichtenfels railway coming from Coburg with the new Ebensfeld – Erfurt line in the direction of Ebensfeld / Nuremberg. It is used together with the connecting curve Dörfles-Esbach the connection of the station Coburg to the new line .

The design speed is 130 km / h. The indicated permissible speed is 100 km / h.

course

The connecting curve is located north of the Weißenbrunn am Forst valley bridge . In the direction of Coburg, it leads out of the high-speed line towards Erfurt at the Weißenbrunn am Forst junction in front of the Höhnberg tunnel at kilometer 99.78 and leads with the Füllbach tunnel initially under the Höhnberg tunnel. It runs southwest of the Füllbachtalbrücke over the Füllbach railway overpass and the 106.5 m long B 303 railway overpass . It then reaches the Eisenach – Lichtenfels railway line and winds about one kilometer east of Creidlitz station at kilometer 135.640 towards Coburg.

The connecting curve, with a gradient of up to 29 per thousand (for passenger trains), overcomes a difference in altitude of around 40 m. There is a noise protection wall on the western side of the route in the Füllbach valley.

The threading into the new line towards Ebensfeld is followed by a simple track change, via which trains from Coburg can get to the regular track towards Ebensfeld. The permissible speed of the new line is 300 km / h after the threading, on the existing line initially 100 km / h are allowed, in Creidlitz station (and further towards Coburg) 90 km / h.

The railway crossing Füllbach is a 90 m long and 7.17 m wide structure that m in spans of 15, 3 x 20 m and 15 m to Füllbach and two farm roads spans. The river bed of the Füllbach was relocated in the course of the construction work. In December 2016, it became known that the structure had moved vertically, which required renovation of the foundation. The bridge's abutments were set 4 cm. The subsoil was stabilized with a cement suppression until June 2017 in order to prevent further subsidence. On July 25, 2017, the structure was checked with a ballast train with a mass of 1,300 tons.

The layout was based on the plan with a standard radius of 1180 m and a minimum radius of 688 m. In the northern connection to the Füllbach tunnel, the connecting curve runs in a radius of 756 m with a 160 mm superelevation .

history

planning

The Niederfüllbach connecting curve was the subject of construction and planning approval sections 1.1 and 1.3 of the new line. The border between sections 1.1 (connection of the new line) and 1.3 (“connection to Coburg”) lay in the northern pre-cut of the Füllbach tunnel.

A route was applied for for planning approval, which was further developed in accordance with the state planning assessment of March 1, 1993. From May to November 1993, a preparatory project coordination took place with the local authorities concerned.

The planning approval decision was issued on June 10, 1996, and the financing agreement was concluded on November 10, 1997. Commissioning followed at the end of 2017.

construction

First the Füllbach bridge was built in 2007/2008. In addition to the railway bridge, the overpass over the federal highway 303 also consists of a trough structure for lowering the federal highway and was completed in September 2010.

For the connection of the connecting curve to the existing route, this was blocked in sections from May 23 to June 14, 2015. Among other things, 2.5 km of track and four new points were installed. Another blockage took place from 9 to 29 January 2017. The originally single-track section of around one kilometer between the threading of the connecting curve and Creidlitz station was expanded to double-track by the beginning of 2017.

As part of a further closure, from June 3 to 18, 2017, the superstructure on the Füllbach Bridge was completed and the overhead line was finally put under tension. With the completion of the closure, the two Coburg connecting curves were put into operation.

Repaired cracks in the concrete in the area of ​​the southern threading (July 2017)

A number of cracks in the concrete of the slab track of the southern threading were repaired in the first half of 2017.

The costs for the connection of the Coburg train station to the new line are put at a total of 30 million euros.

The two Coburg connecting curves were integrated into the expanded Coburg signal box, which is located on the site of the former freight station , from the beginning of 2017 . The contract to expand the signal box, which went into operation in 2008, was awarded in 2015 for 3.3 million euros.

business

After operations began in December 2017, three pairs of ICE trains and eight regional express trains on the Nuremberg – Coburg – Sonneberg line were routed over the connecting curve in each direction on working days. A fourth pair of ICE trains was added to the timetable change in December 2019.

From December 2023, regional traffic will run every hour.

In the third expert draft of the Deutschland-Takt , presented in June 2020, hourly regional and two-hour long-distance traffic across the curve is stored.

technology

The superstructure is partially designed as a ballast superstructure , in the tunnel and at the transition to the new line the track lies on a slab track .

The route is remote-controlled from the Munich operations center via the Coburg ESTW center. The Creidlitz station, which was controlled by an interlocking from 1930, was incorporated into the Coburg ESTW as part of the integration of the connecting curve.

There is an access control signal on the route, which is controlled by an electronic interlocking on the new route.

The transition from conventional control and safety technology ( Ks , PZB ) to ETCS means that trains in the direction of the new line temporarily brake and temporarily fall below the permissible speed. Background: There are two main signals on the curve in the direction of the new line . The first is the ETCS entry into ETCS Level 2, the follow-up signal is the access control signal, which shows "stop" for conventional trains and which can only be passed by ETCS Level 2 trains. Since entry can only take place at the upstream (first) main signal, this always shows "Drive, expect stop", which means that braking must first be initiated. After the successful transition to ETCS Level 2 has become known to the route, the access control signal can be switched to dark and the train can then accelerate again.
