Norske tog AS is currently in the project planning phase for several upcoming procurements related to upgrades of the FLIRT trains. Norske tog intends to introduce a model where lifecycle management is carried out as incremental upgrades/packages spread throughout the train�s lifespan instead of a more traditional mid-life upgrade at the midpoint of the train�s life. As part of this work, we wish to initiate a dialogue with the supplier market to gather relevant information that can help shape the further process.
