Hörmann, Heiterblick and Co develop Europe’s first hydrogen tram and standalone AI tram

Chemnitz, October 4, 2022. Saxon machine makers, automotive engineers and transportation corporations are shaping new worth chains to construct future rail autos within the Free State. The core tasks are the autonomous tram and the primary hydrogen-powered tram in Europe. The hydrogen tram is scheduled to be operational for the primary time in 2025. That is the results of info acquired from “Hörmann Automobile Engineering” from Chemnitz.

The regional worth chain is rising collectively

Hörmann is answerable for the design. “Heiterblick” from Leipzig builds trams. Synthetic Intelligence (AI) needs to implant Chemnitz’s “Fusion Techniques” on the tram. Researchers from the Fraunhofer Institute for Manufacturing Expertise and Utilized Supplies Analysis (Ifam) Dresden and the Institute for Air flow and Refrigeration Expertise (ILK) create progressive options for utilizing waste warmth. Automation options come from “Flexiva Automation & Robotik” of Amtsberg close to Chemnitz. It’s deliberate to conduct check drives of transport corporations in Chemnitz and Görlitz.

H2-Tram: An progressive waste heating system to extend the vary of gas cell trains

The particular demonstration challenge is undoubtedly the “H2-Tram”: a tram powered by hydrogen gas cells, which may additionally attain the outskirts of cities with out air traces. A particular characteristic of the brand new – and already undesirable – recycling techniques is the waste warmth produced by every gas cell in addition to the electrical energy. Engineers need to use this warmth to warmth the trams within the winter and funky them in the summertime. This could cut back hydrogen consumption. Venture companions anticipate that “the brand new complete method will enhance scale by 25%.”

The primary driving check in Görlitz in 2025

“This places us forward in Europe,” emphasizes Hormann engineers. There may be already a variety of curiosity from worldwide rail building teams who additionally need this expertise. The Chemnitz-based firm additionally needs to create a “digital twin” of the tram in a pc through the design part, the place parameters reminiscent of consumption, driving habits and acceleration could be examined earlier than the primary bodily check drive. In 2025, the primary actual H2 trams in Görlitz ought to start its check drive. Sooner or later, this expertise may additionally be usable – with a modified monitor width – for regional roads on which rails have been laid however diesel locomotives or railcars have been navigating till now. However within the rail sector, there are already competing options to rail.

“Smartram”: AI whereas driving, people can intervene remotely

The second significantly technically formidable growth challenge by Hörmann, Heiterblick and different Saxon companions is “Smartram”. Right here, engineers are engaged on an autonomous tram that, if wanted, could be remotely managed by a human from a management middle if the AI ​​feels overwhelmed. The engineers selected a hybrid answer: with its many sensors and analysis electronics, the “Smartram” should be capable of orient itself by itself railroad and acknowledge obstacles on the one hand, and alternatively use the “good” infrastructure on the fringe of the monitor for navigation and schedule planning .

AI Tram Leads Guests to the Capital of Tradition in 2025

The prototype is to finish an preliminary driving check at a check web site operated by Chemnitz for public transportation. Testing is taken care of by the competency middle for railway and aviation expertise Dresden in Bavaria “Industrieanlagenbetriebsgesellschaft” (IABG). When Chemnitz welcomes many guests because the “European Capital of Tradition” in 2025, it is usually assumed that the primary shuttle excursions on town’s specifically managed roads will probably be doable. Sooner or later, driverless trams, that are monitored remotely from the management middle, may cut back personnel prices on native public transport. This in flip may – maybe in a joint answer with the H2 tram – make extra tram connections to suburbs and villages extra reasonably priced for municipalities.

Hörmann Chemnitz originated from the VEB . design challenge

For each tasks, the primary protagonists can draw on a long time of expertise. In terms of designing progressive, full rail autos, the Chemnitz-based firm cannot be simply fooled, says Volkmar Vogel, who based the engineering agency in 1989 from a VEB Karl-Marx-Stadt design challenge and eventually merged it with the Hörmann Group. . As well as, Saxon Hörmann builders additionally use their experience in associated areas of expertise: for instance, they’re coping with new light-weight building ideas for trains and trams, engaged on an ultra-light wagon chassis with built-in leaf springs, however additionally they have kits for bikes from BMW and MZ and different designer companions.

Heiterblick was as soon as a workshop for a public transport firm in Leipzig

Alternatively, Heiterblick goes again to the previous principal workshop of the transport firm Leipzig, which was fashioned in 2004 as a producer of its personal railcars. As we speak, the corporate, named after one of many provinces of Leipzig, has about 100 workers.

Hecht & Co: Saxony’s lengthy custom of tram building

As well as, Saxony and Central Germany have at all times been conventional websites for the development of progressive trams. One instance is the “Large Hechtwagen”, which was a trend-setter on the time and was constructed about 100 years in the past by Dresdner Strassenbahn AG, the wagon-builder Christoph & Unmack of Niesky and the Sachsenwerk in Dresden-Niederselitz. Waggonbau Görlitz, Lowa Werdau, and Gothaer Waggonfabrik additionally constructed trams within the East German period. The CMEA’s labor division, throughout which the Tatra trams then dominated the Jap Bloc, interrupted the Saxon and Central German tram-building traditions because the late Nineteen Sixties. After the reunification, Deutsche Waggonbau AG in Bautzen, Niesky and Görlitz, for instance, started constructing trams and railways once more – first underneath the supervision of Bombardier, then Alstom. The way forward for the Saxon railway building websites was shaken repeatedly. Nonetheless, works in Görlitz and Bautzen repeatedly acquired orders to construct trams. This additionally features a €197 million order from the Dresden public transport firm to construct the brand new NGT DX DD mild rail automobile for the Saxon state capital.

As a full-fledged tram producer, “Heiterblick” Leipzig continues to be comparatively new on this subject, however has already acquired quite a lot of massive orders. In 2021, for instance, residents of Leipzig, along with their companion Kipi Electrical, acquired an order totaling 600 million euros for the event and building of a brand new era of trams from transport corporations in Zwickau, Görlitz and Leipzig.
