In-carriage solutions

In-carriage solutions
Increased complexity in train systems has increased car body wiring. This in turn impacts on the space required for extra wiring and increases weight, which has an adverse affect on performance and cost of ownership. This means that wiring the individual components is becoming increasingly challenging. Under these conditions, the use of thinwall and lightweight cables is essential to meet the technical challenges of the market while simultaneously reducing the amount of combustible material and thus potential fire hazard.

To transmit signals and power within the train, HUBER+SUHNER has been developing, constructing and manufacturing an extensive range of single cores, multicore cables and inter-vehicle jumper systems for many years. Bulk cables are just as much a part of the offering as pre-assembled cables or customer-specific cable systems. All products are completely halogen free, non-toxic, low-smoke, and resistant to abrasion and fire. Therefore, they provide a very high degree of safety for all passengers throughout the entire life cycle of the rail vehicle.

Application areas
  • Driver's desk
  • Traction motors
  • Air conditioning
  • Control and safety equipment
  • Bogie
  • Complete coach harnesses
  • Control panels and cubicles
  • Lighting systems
  • Inter-vehicle systems

Control cables


As one of the leading providers of standard and customer-specific cables and cable systems, HUBER+SUHNER delivers the optimum solution for the wiring of rail vehicles such as regional trains, high-speed trains, underground railways, trams and locomotives.

Its many years of experience in the rail sector give customers the reassuring knowledge that, with HUBER+SUHNER, they will receive innovative products that work perfectly.

RADOX railway cables meet the demanding requirements of the rail market and has been tested successfully in accordance with European cable standards EN 50264 and EN 50306, as well as standards GOST 20.57.406-81, Method 204-1 and GOST 17491-80. This gives customers an additional safety factor.




The new RADOX EN 50306 railway cables are based on the recently developed, halogen-free, electron-beam crosslinked insulation system RADOX EI 306 with the sheath material RADOX EM 104, and comply with the specifications of standard EN 50306 (hazard level: HL3; property level: M).

All cores and cables have tin-plated stranded copper conductors and halogen-free insulation sheaths and materials. The cores and cables are designed for unprotected installation (Class E) or for protected installation (Class P). They are intended for permanent installation in rail vehicles or for applications in which a limited alternating bending stress occurs during service.
