Integra Signum
Integra Signum AG , a company headquartered in was Wallisellen , the most of at interlockings , train control systems and signal systems delivered in Switzerland.
history
The company was founded in 1919 by a Swiss consortium under the name Signum AG . The origins of the company go back to the signal box factory Wallisellen , which was established in 1905 as a branch of the Bruchsal machine factory . When the company was founded, the signal box factory was transferred to Signum AG as a holding of the parent company. Military considerations were behind this, because track plans should not fall into foreign hands. In the post-war period, Integra AG , which was established in 1945, was responsible for development, project planning and sales, while production remained largely at Signum AG.
From 1991 onwards, Integra Signum AG, which arose from the merger of the companies Integra and Signum, worked with Siemens-Albis AG after a previous collaboration with Ericsson without capital links failed. Siemens took over 51 percent of the shares in Integra-Signum. The in-house development of electronic signal boxes only for the Swiss market Integra Signum could not afford. In 1996 Integra Signum was integrated into Siemens Schweiz AG. The plant is the Swiss headquarters of the Siemens Mobility and Logistics and Rail Systems divisions . After a merger with the French company Alstom failed in spring 2018, the mobility sector was spun off from the group and now operates as Siemens Mobility AG. Siemens AG continues to hold the majority of the shares.
Products
The company initially built mechanical and from 1939 electrical signal boxes . Integra Signum became famous for the development and manufacture of the Integra-Signum train protection system , which was introduced by the Swiss Federal Railways in 1933 . In addition, train control systems have been developed for Swiss narrow-gauge railways .
In addition, many Swiss were stations with track the switchboard of type Domino equipped, the setting table surface consists of pluggable components square of 40 mm side. With the Domino 55 interlocking, driving and shunting routes can be set with push buttons. Edge protection measures for routes to be set and the control of the signal aspects are carried out automatically. The routes are broken up after the train has traveled on them. Domino 67 also enables the storage of set routes. As soon as the first route is cleared, the second runs automatically. Domino 69 was specially developed for the needs of smaller train stations with simple operating conditions and without closed shunting routes. Like all Domino interlockings, this type also works with relay technology. Operating processes can be automated with a programmable logic controller (PLC).
