The SBB Reuss Bridge Turgi is the second oldest railway bridge in Switzerland that is still in operation.

The SBB Reuss Bridge Turgi is a railway bridge on the Zurich – Baden – Brugg – Aarau line and crosses the Reuss in the canton of Aargau in Switzerland . It is the second oldest railway bridge in Switzerland that is still in use.

It is located at route kilometer 28.7 of line 710 Zurich HB - Brugg AG of the Swiss Federal Railways SBB around 500 m west of the Turgi station at the confluence of the Reuss into the Aare , on the municipal boundary between Gibstorf and Windisch and at the floodplain protection park of the canton Aargau in the moated castle Switzerland .

context

The government of the canton of Aargau approved the routing of the Swiss Northeast Railway (NOB) between Baden and Brugg in 1854 and at the beginning of 1855 had rafting and longitudinal shipping on the Reuss suspended for four months so that the foundation work for the Turgi railway bridge, the most important structure on the route, could be carried out could become.

The construction of the bridge

The building contract with the first contractors, Messrs. Wachter & Haug, building contractors from Leutkirch im Allgäu, who had taken on the difficult construction site, was canceled by the NOB management in June 1855. The two-lane bridge was entrusted to the work group Locher, Näff & Jäger (the company of master builder Johann Jakob Locher and engineer Ferdinand Adolf Naeff with the local master builder Friedrich Jäger from Brugg) four months later . It was first put into operation on September 29, 1856 by the NOB together with the railway line as a single track.

The type of construction of the bridge

Because of the high weight of the trains and their braking and starting loads, stone bridges with stiff and low-vibration dimensions, as they had proven themselves in road construction, were often used in railroad construction in the era before reinforced concrete construction. This is also the case with the SBB Reuss Bridge Turgi.

The arch bridge is made of natural stone. The outer shell consists of precise block house stones made of limestone sandstone and the filling is made of rubble stones. Thanks to the narrow joints, the bridge looks like it is made of one piece even from a short distance. The arches with a large span and low height make them appear light and elegant.

The bridge is 93 m long and 9.65 m wide with a total span of 73 m. The dimensions (radius = 19.4 m, arch height = 3.6 m and span = 25.2 m) of the three circular segment arches are identical. The two 8 m high and 3 m wide river piers, made of blocks, stand on solid foundations that are piled deep in the river bed and caulked with rubble blocks to prevent clogging.

Situation today

The Reuss Bridge Turgi has been owned by the Swiss Federal Railways (SBB) since the Swiss Northeast Railway was nationalized on January 1, 1902 .

These electrified the Zurich – Olten railway line in 1925 and attached catenary yokes to the abutments of the SBB Reuss bridge . In the meantime, a portal mast has been added in the central arch .

During the Second World War , the SBB-Reussbrücke was in the area where the Swiss Army operated the Limmat line . The machine gun bunker at the mouth of the Reuss and the explosive chambers in both pillars date from that time .

The carriageway , which has been extended to double lanes since 1862, as planned when the bridge was built, has been on a deck made of reinforced concrete since 1957. It ensures the sealing of the bridge, which was renovated at the same time, and allows a double lane with the safety clearances that apply today. Since then, a pedestrian crossing has crossed the Reuss on its underwater console, and footbridges at the abutments ensure free passage along the two-sided bank paths.

The footbridge over the river is part of the Limmat-Wasserschloss industrial culture trail , whose technical and historical monuments include the SBB-Reussbrücke Turgi.

In 1989, the SBB carried out a comprehensive renovation of the track. With that, the SBB-Reussbrücke was ready to withstand the enormously increased axle loads, travel speeds and density of the sequence of today's train compositions for many years again.

The bridge is located at the Brugg-Stilli moated castle in the canton of Aargau, a floodplain area of ​​national importance .

Remarks

  1. The oldest railway bridge still in operation is also on line 710. It is the original bridge of the " Spanish Brötli Railway " opened in 1847 over the Schäflibach in Dietikon. The small structure is now covered by the mighty road structure of the double lane.
  2. At that time the Turgi railway junction was still a part of the village of Gibstorf , but emancipated itself and in 1884 became an independent municipality.
  3. Nicola Siegloch , Stadtarchiv Leutkirch im Allgäu reports: " According to the trade tax cadastre 1847-1876 (Stadtarchiv Leutkirch B 701) there was " [...] " a master mason and stone mason named Johann Jacob Wachter. He was born on October 18, 1815 in Bernstadt, Oberamt Ulm, born, received citizenship in Leutkirch in 1840 and died in Leutkirch on May 20th, 1869 (Leutkirch City Archives B 775 Citizen List). An obituary and the obituary notice in the Allgäuer Bote dated May 26th, 1869 suggest that he was a capable man Entrepreneur and businessman traded "[...]". The trade was deregistered upon his death. "[...]". The name Haug [does not] appear, it could be "[...]" from outside the company Trade business partners ".
