We are the ideal partner to ensure availability, reliability, safety and sustainability of railway vehicles.

What can we do for you?


Extensive experience in short, medium and long-cycle preventative maintenance for all types of bogies. We have the specific means and tools to provide the maximum quality and safety in our overhauls.

  • Disassembly
  • Cleaning
  • Non-destructive testing
  • Dimensional control
  • Check of all bogie components
  • Final assembly
  • Functional checks

We offer the option to redesign supports, machined parts and adaptation of the equipment to new requirements or improvements.

We work with the best suppliers for the supply of the systematic spare parts, appropriately chosen and adapted to each bogie model. We take charge of transport services management, blast cleaning and maintenance of the main subassemblies.

What can we do for you?


Long-cycle maintenance of automatic and semipermanent couplers to guarantee the extension of their useful life and proper functionality, as well as the overhaul of the equipment that may have been subjected to unanticipated loads.

Maintenance based on technical standards and maintenance plans, dimensional analysis of the non-systematic replacement parts subject to wear. We guarantee the absence of fatigue cracks by carrying out non-destructive tests as well as the leak-tightness of pneumatic and electrical circuits.

The absence of anomalies in all the components is checked using the same techniques used in long-cycle maintenance, and it is verified that the elastic behaviour of the components involved in impact absorption continue to work within their nominal values.

We carry out quasi-static elastic behaviour checks of equipment using a programmable test bench that plots the reaction force as a function of the applied displacement, which allows the results to be checked with their nominal curves in order to guarantee their correct condition, assembly and maintenance.
