Railway technology

Fire-retardant components for railway technology

Railway technology is crucial to public transport and ensuring that the rail network and trains continue to run without issues means they need reliabile, robust and durable components, that fulfil high quality requirements. Requirements such as: the fire protection standards EN 45545 or NFPA 130. Our motion plastics meet these demands of railway technology and are lubrication-free, which minimises maintenance effort and costs.
Benefits of igus® products in railway technology:

Maintenance-free for 24/7 use
Low noise and low vibration
Easy assembly
No minimum order quantity
Predictable service life

Success stories

IdeasTrain: linear bearings for e-scooter lift at Deutsche Bahn

The IdeasTrain is an initiative of Deutsche Bahn dedicated to tomorrow's passenger transport. One of the concepts developed here: an e-scooter lift for space-saving suspension and charging of the scooters during the train journey. The two-wheelers are hooked into a bracket and can be moved up and down electrically on a linear axis. This is where drylin linear systems and drives for lubrication-free operation come into play.

Doors on the Metro del Valles light rail line in Barcelona

Space-saving light rail doors with igus components

Developing compact passenger doors for new light rail vehicles on the Metro del Valles line in Barcelona is the job of Masats, a Spanish company. Engineers used igus chainflex control cables and e-chains in the door opening mechanisms. The special control cable design allows extremely small bend radii (just 20 millimetres). The cables are thus ideal for passenger doors that are among the most space-saving systems on the market.

drylin R linear rail in a cleaning vehicle

Lubrication-free linear bearings with high rigidity in a tunnel-cleaning vehicle

For the metro in Riyadh, Saudi Arabia, Zweiweg International developed a two-way cleaning vehicle featuring especially flexible cleaning technology. Linear systems from our modular construction kit also contribute to this technology. The linear technology, which requires no lubrication or maintenance, is compact when retracted, but allows for a long extension that does not yield too much under the high water pressure. Since it is lubrication-free, dirt and dust do not affect its functionality.

drylin® lead screw drives keep gap bridging moving on trains

Sliding steps must work in all weather and be safe, so that even passengers with prams or limited mobility can get on and off without assistance. Lubrication-free and thus maintenance-free dryspin high helix lead screws and nuts from igus are central components of an innovation from Knorr-Bremse GmbH, Division IFE. They are resistant to corrosion and media and ensure a long service life ‒ at significantly reduced costs.

Maintenance-free shaft guides in doors of high-speed train

These high-speed trains travel between Beijing and Shanghai at speeds of up to 350km/h. The outer doors are guided with shaft guides from the drylin R series. The advantage: the liners of the linear bearings are made of lubrication-free and maintenance-free iglidur. In addition, the bearings move particularly quietly and work reliably even in the sometimes adverse weather conditions.
