Over the next three years, HUBER+SUHNER will supply RADOX® cables for the series production of 54 carriages for new metro trains in a major Russian city. This is the first order for HUBER+SUHNER from the Russian railway market based on the new approval.

The new trains are being manufactured in a joint venture between Russian and Czech mechanical engineering companies. They consume 30 per cent less energy whilst also providing more comfort for passengers. HUBER+SUHNER advised both companies on technical matters and supplied the cables for testing. Following the successful completion of these tests, HUBER+SUHNER has now been appointed as the cable supplier for the production of all the new metro trains.


Almost the full range of RADOX® rail cables, including RADOX® data bus cables and RADOX® signal and power cables are used in the trains. They are particularly robust and safe, providing a long service life of up to 40 years whilst also being able to withstand both high and low temperatures (from -50 °C to 120 °C). The cables will be used for almost all of the systems in the trains, such as the power supply for the lights. The trains also feature a modern passenger information system in which the cables are used to transmit the data.


This order follows the official certification of the cables at the end of 2013 as meeting the requirements of the Russian railway market. This certification of the RADOX® rail cable portfolio was a major factor in the decision to select HUBER+SUHNER as supplier. “The project is a milestone for HUBER+SUHNER. For the first time, we have been able to use our foreign-produced rail cables on the Russian metro railway market for the series production of metro trains. Our work toward certification over the past few years and the wide range of tests have been rewarded,” said Alexey Chernychev, Business Development Manager at HUBER+SUHNER Russia.



HUBER+SUHNER is the world's number one supplier of connectivity solutions for railways and this order sees it continue to build on this strong position. The company has extensive experience in the development and production of cables and cable systems for railway applications. In addition to connectivity solutions for supplying power, HUBER+SUHNER also develops cables and antennas for communication networks in trains and between trains and the track. Fiber optic cables are used for data transmission in passenger information systems and for video surveillance, while antennas provide passengers with on-board internet access. HUBER+SUHNER therefore provides comprehensive solutions to provide passengers with excellent connections in trains.
