Why are trains modernised?
A train can be modernised many times during its lifetime. Modernising a train helps
to extend its lifetime (by 15 to 20 years) or add new functions.
The modernisation can have different objectives:
Modernising a train serves a number of purposes:
– To improve the aesthetics of the exterior or interior (paint, fabrics, etc.) in order to restore the train to good condition or bring it up to date;
– To update or replace subsystems with more modern and more efficient equipment: the lifespan of some subsystems does not exceed 10 or 15 years;
– Meet new standards: access to persons with reduced mobility (PRM), elimination of certain materials, etc.
– To bring the train back into circulation: install new features.
