The Schönbuchbahn is a 16.978-kilometer standard-gauge branch line in the Stuttgart region . It is operated by the Württembergische Eisenbahngesellschaft (WEG), the railway infrastructure company is the Schönbuchbahn (ZVS). In 2013, an operating performance of around 400,000 train kilometers was achieved, with up to 8,000 passengers per day. In the wedge station Schönaicher First - today Böblingen Zimmerschlag - a branch line to Schönaich branched off between 1922 and 1959 . Freight traffic has not taken place since the 2000s.

history

State Railroad Time

In order to open up the Schönbuch clearing between Stuttgart and Tübingen for rail traffic, the Royal Württemberg State Railways planned the construction of a branch line from Böblingen via Holzgerlingen and Weil im Schönbuch to Dettenhausen . After construction began in 1909, the first section from Böblingen to Weil im Schönbuch was put into operation on October 16, 1910. The second section to Dettenhausen followed on July 29, 1911.

As a result of the restrictions on the branch lines of the Deutsche Bundesbahn (DB), from May 29, 1965, no more pure passenger trains ran between Böblingen and Dettenhausen; the majority of passenger traffic was taken over by rail buses . Only one freight train with passenger transport (GmP) ran until the end of September 1966, with only 90 passengers using the route every day in that year. After that only pure freight trains ran, in 1988 the Deutsche Bundesbahn finally applied for the line to be closed . After the district of Böblingen showed interest in taking over the line, it did not pursue its intention to close it any further. Ultimately, freight traffic between Schönaicher First and Dettenhausen ended on April 28, 1990, but was continued until Schönaicher First. The Schönaicher First – Dettenhausen section was not de -dedicated at that time , but was only out of service from then on.

Takeover by the Schönbuchbahn association

When it reopened in 1996, the Böblingen platform for the Schönbuchbahn could only be partially increased

The population along the route did not want to come to terms with the cessation of passenger traffic and the threat of total closure. However, the numerous action groups, resolutions and resolutions of the local councils of the neighboring communities between 1959 and 1986 were unsuccessful. It was not until May 30, 1988 that the matter began to move again. The district of Böblingen and the district of Tübingen commissioned the Württembergische Eisenbahngesellschaft with the preparation of an expert opinion on the possibility of resuming passenger traffic on the Schönbuchbahn. This report from September 1989 forecast 2500 passengers a day, 25 percent more than with bus transport.

Thereupon, in autumn 1992, the Baden-Württemberg Ministry of Transport approved the restart and classified the project as worthy of support. As the sponsors of a future railway operation, the districts of Böblingen and Tübingen decided to reactivate the line in July and October 1993, respectively, and founded the Zweckverband Schönbuchbahn (ZVS) on December 21, 1993 , in which Böblingen and Tübingen hold 80 percent shares. On December 28, 1993, he bought the line from the Deutsche Bundesbahn for the symbolic price of one D-Mark plus VAT. Starting funds for neglected repairs to the track and other starting aids were not granted. After a limited tender for the construction and operation of the railway, to which six transport companies submitted bids, including Deutsche Bahn AG , WEG was awarded the contract on July 6, 1994. The tender called for 27 pairs of trains Monday to Friday, 14 on Saturdays and six on Sundays and public holidays.

In 1995, the WEG began with the extensive expansion of the route, which - without the procurement of new vehicles - cost 14.6 million euros and was funded by the Municipal Transport Financing Act (GVFG). In detail, the following measures were carried out:

• Strengthening the track and increasing the line speed from 50 to 80 km / h
• New construction of six stations for the shortest possible footpaths to the next train station, including Holzgerlingen new construction as a crossing station with fallback switches
• Upgrading six existing stations
• Equipping all twelve stations with 76 centimeter high platforms for stepless boarding as well as new shelters
• technical security of twelve level crossings with barriers or traffic lights
• Demolition of five level crossings from footpaths and cycle paths to circulation barriers
• Closure of four level crossings
• Construction of an underpass instead of a level crossing
• Refurbishment or new construction of six bridges
• Creation of four sidings for freight traffic
• Construction of a vehicle storage hall with workshop in Dettenhausen
• Establishment of train control radio
• Installation of ticket machines

Park-and-ride facilities were also built as part of the reopening . Only in Böblingen station could the platform used by the Schönbuchbahn (track 1) only be partially raised, so that only the first entry in the direction of Dettenhausen was barrier-free.

reopening

On September 28, 1996 the Schönbuchbahn was ceremoniously reopened, but for technical reasons the scheduled operation was not resumed until December 1, 1996. The travel time on the entire route was 24 minutes at that time, the following timetable was available:

• Monday to Friday: every 30 minutes from 5:02 a.m. to 10:02 p.m., then every hour until closing time at 0:02 a.m.
• Saturday: Start of operations at 7:02 a.m., 30-minute intervals from 8:02 a.m. to 4:02 p.m., then hourly until operations close at 0:02 a.m.
• Sundays and public holidays: every hour from 8:02 a.m. to 10:02 p.m.

In Böblingen station there was a connection to the Stuttgart S-Bahn , in Dettenhausen to regional buses in the direction of Tübingen. In the course of reopening, the Schönbuchbahn was integrated into the Stuttgart Transport and Tariff Association (VVS) and initially referred to as the R72 line. The municipality of Dettenhausen was also included in the VVS tariff area, although it is located in the Tübingen district.

On the first working day after reopening, December 2, 1996, 3740 passengers were counted. Previously, 2000 passengers per day were counted on the bus connection along the route. In mid-2000, an average of 5500 passengers were counted, and the trains were often overcrowded. However, it was not possible to compress the cycle on the single-track route with a passing point . In 2001, the platforms were lengthened so that three-part multiple units could also be used - mainly for school traffic - and the wagon hall in Dettenhausen was enlarged.

During the summer vacation of 2003, the traffic was temporarily provided for the first time as a replacement rail service in order to be able to carry out urgently needed renovation work. During the first renovation of the line, old, still usable rails and sleepers were used, which were replaced with new material. In addition, several problem areas in the substructure, mainly on railway embankments and bridges, have been eliminated. In the spring of 2003, 6800 passengers were counted on weekdays. In April 2008, over 7,400 passengers used the Schönbuchbahn every day.

In 2010, 4,200 passengers per day were counted in the northern section of the route and an increase to 6,200 passengers per day is expected by 2025.

In 2011, the ticket machines at the stations were dismantled and new ones were installed in the railcars.

Electrification and partial double-track expansion

In the 2000s, the number of passengers on the route continued to increase. In 2012, more than 10,000 passengers were carried on working days. For this reason, efforts have been made since 2009 to electrify the line with 15 kV alternating current and to double-track the sections Böblingen - Böblingen Danziger Straße and Böblingen Zimmerschlag - Holzgerlingen Hülben in order to set up a 15-minute cycle between Böblingen and Holzgerlingen. On the remaining section to Dettenhausen, it should stay at 30-minute intervals. It was also planned to upgrade to a top speed of 100 km / h, to build all of the signaling systems and to convert all platforms to a uniform length of 85 meters and a height of 76 cm above the top of the rails .

The standardized assessment for the expansion resulted in a benefit-cost indicator of 1.42. At that time, the state of Baden-Württemberg promised funding of 37.5 million euros, while the Schönbuchbahn association had to raise around 38.5 million euros as a contribution. On March 9, 2015, the transport committee and on March 10, 2015 the finance committee of the district council approved the state's funding offer.

The plan approval procedure was divided into four sections:

1. Construction of a new depot with workshop and signal box in Böblingen between the train station and the Danziger Straße stop. Conversion of the vehicle hall in Dettenhausen into a pure storage hall. The planning approval decision was issued on September 25, 2015.
2. Böblingen train station to Zimmererschlag stop: New construction of a second track from up to route kilometer 1.55 and new construction of the Danziger Strasse stop, route kilometer 1.2 to 1.3. Elimination of the level crossing at Herrenberger Straße in Böblingen.
3. Zimmererschlag stop to Holzgerlingen train station. Construction of a second track between the Zimmerschlag stop and Holzgerlingen train station and a new platform at the Zimmerschlag stop. Abandonment and dismantling of the Holzgerlingen Nord stop, replacement by the new Holzgerlingen Hülben stop approx. 350 meters further south. Dismantling of the existing platform in Holzgerlingen station and replacement with a new central platform. Elimination of the level crossing at Böblinger Straße in Holzgerlingen. The planning approval decision for sections 2 and 3 was issued on June 16, 2016.
4. Holzgerlingen station to the end of the line in Dettenhausen: Extension of the platforms, improvements to the track layout and drainage systems.

Expansion work officially began on November 11, 2016 with the groundbreaking ceremony for the new depot at Böblingen station. The cost estimates at that time were around 93.8 million euros, of which 20 million euros for the depot. On March 30, 2017, the Schönbuchbahn association awarded the expansion of the line to Leonhard Weiss for almost ten million euros . The route was closed for construction work from July 30, 2017. Construction work on the Herrenberger Strasse level crossing in Böblingen began on August 31, 2017, and on October 18, 2017 on the Böblinger Strasse level crossing in Holzgerlingen.

In July 2018 it became known that 80 out of 457 catenary masts were unusable and had to be replaced due to a planning error . This led to a construction delay of around four weeks, the commissioning should take place at the end of December 2018 instead of the beginning. The Zweckverband announced that it would take recourse against the planner for the damage of 2.25 million euros. With a forecast total cost of 91 million euros, the project was 0.85 million euros above the previous estimate. The additional costs had become necessary in order to strengthen the route on the stony ground near Holzgerlingen against vibrations.

The route between Holzgerlingen and Dettenhausen went back into operation on February 24, 2019. The restart between Böblingen and Holzgerlingen was initially planned for December 2018, but after several postponements it did not take place until December 14, 2019. During the closure, a replacement bus service was carried out with buses. In the course of the reopening, the route was given the new line number RB 46.

The cost of expanding the infrastructure amounted to 120 million euros. The Zweckverband hopes for an increase in passengers from 8,000 to 14,000 passengers. The 15-minute cycle was introduced in December 2019.

Regio-Shuttle RS1

Railcars in freight service, 2005

Two class 426 railcars on the opening day of electrical operations in Dettenhausen

Between regionalization and electrification, only Stadler Regio-Shuttle RS1 diesel multiple units were used, which were also used as towing units in freight transport until it was discontinued . When it reopened in 1996, four units were initially available:

• VT 430 "Dettenhausen"
• VT 431 "Because in the Schönbuch"
• VT 432 "Holzgerlingen"
• VT 433 "Böblingen"

In 2001, the VT 415 “Schönbuch” and VT 423 “ Schaichtal ” railcars were finally purchased , but they were not brand new, but were taken over from the Strohgäubahn and Wieslauftalbahn as part of a ring swap .

In June 2013, the Zweckverband Schönbuchbahn tendered the procurement of ten electric multiple units, with the option of three more identical trains to be delivered later, across Europe. The delivery should take place by September 2017. Since none of the providers in question had suitable multiple units on offer, the tender was canceled and, under changed technical conditions, the procurement of nine light electric multiple units, with the option of two more trains, was put out to tender. CAF was awarded the contract for 53 million euros. The nine trains of the 0455 series ( CAF NEXIO ) are to be delivered from December 2020. They will be 40 meters long, have 94 seats and 118 standing places and a top speed of 100 km / h. The first multiple unit arrived in Böblingen at the end of June 2020 and will initially be used for test and acceptance runs planned until the beginning of 2021. The commercial commissioning of the vehicles should now take place by the end of 2021.

Until the new vehicles are delivered, four used electric multiple units of the 426 series rented by Deutsche Bahn will operate in mixed operation with the existing regional shuttles, with the rental vehicles mainly being used during the 15-minute intervals during rush hour. Their first class of car is outclassed, and they are permanently manned by a train attendant who, due to the lack of machines and validators, is responsible for selling and stamping tickets.

Planning

In the regional plan there is an option to connect the Schönbuchbahn trains to Stuttgart. To this end, the area is kept free for a third track from Böblingen to Stuttgart. The Böblingen district office considers an extension beyond Dettenhausen to Tübingen to be uneconomical.

Role model

In the meantime, the Schönbuchbahn has become a prime example of the successful takeover of a state branch line by local authorities. Numerous visitors and delegations from all over Europe, representatives of municipal associations and local initiatives, parties and universities visit the Schönbuchbahn to find out more about the concept. However, the subsidy requirement of the association also rose from the initially planned 300,000 to 1,600,000 euros (2003). The reasons for this are the above-mentioned, originally not planned renovation work, the expansion of the offer (but far below average in relation to the increase in passenger numbers) and, above all, the poor participation in the VVS fare for the operator, which is based on the low passenger forecasts.

Movie

The Schönbuchbahn was presented in episode 234 of the SWR series Eisenbahn-Romantik .
