Railway Engineering Technology

Railway engineering involves the design, construction, operation, and maintenance of railway systems. This includes; track engineering, signal and control systems, power supply, infrastructure and more.

Railways use technologies such as digital signalling and control systems, electrification and energy supply, and IoT sensors with predictive maintenance to keep networks safe and efficient. They also rely on advanced materials, robotics, and automation for inspection, depot operations, and rolling stock reliability. Together, these innovations make rail transport faster, more sustainable, and more reliable for passengers and freight.

Railway maintenance is the ongoing inspection, repair, and replacement of tracks, trains, and supporting infrastructure to ensure safe and reliable operations. igus® manufactures and supplies many components for railway engineering that feature lubrication‑free properties, thereby minimising maintenance requirements.

Railways rely on several types of bearings to ensure smooth, reliable operation, and igus offers specialised options designed for demanding environments:

• Plain bearings – High heat‑resistant and maintenance‑free thanks to embedded solid lubricants, ideal for heavy‑duty railway applications.
• Slewing bearings – Enable smooth rotational movement in components such as seating systems, doors, and inspection equipment.
• Self‑aligning bearings – Compensate for misalignment and reduce stress on shafts, ensuring long service life under dynamic loads.
• Linear slide bearings – Provide low‑friction, maintenance‑free motion for sliding mechanisms in inspection devices, depot automation, and passenger systems.
