China's biggest train producer and world's largest wind tunnel go big!

CGTN Europe

Train travel may be a greener way to get from point A to B but it's often hampered by extreme weather events. Manufacturers, including China's biggest trainmaker, are using the world's largest wind tunnel to weatherproof their designs.   Johannes Pleschberger reports from Austria.

00:00At very low temperatures, rubber components get stiff and break apart.

00:06Entire electronic systems can fail too.

00:12One part of our rain system, here we are controlling the water flow

00:16and can let it rain or make an ice rain as well.

00:22Gabriel Haller is the mastermind behind the world's only climatic wind tunnel

00:26that can fit an entire train.

00:28One click is enough to lower the temperature to minus 45 degrees Celsius

00:33or increase the wind speed to 250 kilometers per hour.

00:38We do not have to wait for the next extreme winter.

00:43We can simulate it.

00:45We are guiding the air through a fan, downstream,

00:49then to the test section and there we are testing the test objects.

00:54China's state-owned train manufacturer CRRC

00:57has been using the Viennese wind tunnel for over 10 years,

01:01most recently to test the windscreen wipers of its Bison locomotive.

01:06The multiple voltage freight train, which can operate on different countries' rail tracks,

01:11is to begin running in Hungary soon.

01:13It will be operated by a subsidiary of Austrian Railways.

01:18CRRC has big plans for Europe's competitive railway market.

01:22After basing its continental headquarters here in Vienna,

01:26China's biggest train producer has bought a locomotive production site in Germany

01:31and is now test-driving its Bison train in Hungary,

01:34ready for operation across Central and Eastern Europe.

01:39In 2023 CRRC and Vienna's RTA wind tunnel

01:43signed a memorandum of understanding to intensify future joint research.

01:48Research cooperation with CRRC is dealing with snow and ice accumulation on certain components

01:55and we can validate their research activities by doing real tests.

02:02In extreme weather, the proper functioning of pantographs,

02:06the train top apparatus which collects power from an overhead line,

02:09can prevent delays and line failures.

02:12Vehicle tests like the ones in the Austrian capital are essential not just for reliability

02:17but also for safety during adverse weather conditions.

02:20Johannes Blechberger, CJTN, Vienna.
