Intelligent system for tilting trains


The Intelligent System for Integrated Tilting (ISIT), developed by rolling stock manufacturers CAF (Basque Country), is a tilting system which activates at the required moment and manages to reduce the centrifugal effect suffered by passengers when a train negotiates bends. Or, in other words:

  • Cuts journey times (26% on the Santiago-A Coruña run in Galicia)
  • Enhances passenger comfort
  • Anticipates the curved sections of track and eliminates delays
  • Always functions without distortions, in any circumstances, whatever the grade of track.

Thus, the Intelligent System for Integrated Tilting developed by CAF provides numerous advantages:

  • Cuts in at the required moment, because it continuously detects the exact position of the train on the line and knows the features thereof (curves, etc.)
  • Achieves maximum use of limits
  • Achieves an optimum inclination of the train body, with tilting of up to 8 degrees, depending on the geometry of the track and on the rest of traffic conditions
  • Takes up minimum space and is lighter in weight
  • It is clean and silent, contributing to improving the environment
  • Operates with both electric and diesel trains, making the ISIT system a versatile one
  • Reduces track maintenance requirements

In short, ISIT manages to provide a vehicle that takes curves at greater speed, because these bends are anticipated, thanks to an additional inclination of the body of the vehicle with respect to the track.

Im Focus: ILA 2018: Laser alternative to hexavalent chromium coating

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
