The national railway company of Luxembourg (CFL) became the first company in the country to receive ISO 19650 certification, paving the way for the development of an integrated digital twin of the entire railway network. Railway Supply magazine writes about this with reference to RailTech.


The certification recognizes the firm’s expertise in Building Information Modeling (BIM), and CFL predicts that increased use of BIM will simplify construction project processes and create a wide range of 3D digital twins representing all the diverse components of the national rail network.

Relying on laser scanners and 3D modeling software, CFL has already implemented BIM in the development of the Pulvermühle viaduct, the passenger buildings of Luxembourg and Rodange stations, and P+R Mersch. The first building to be fully designed and built using the BIM method in Luxembourg was Wasserbillig in 2021.

“BIM is leading to a new paradigm by providing real-time insight into the consequences of choices made when designing a building, for example,” says Mark Wengler, CEO of CFL.

The firm has set itself the goal of completing an integrated digital twin of the entire Luxembourg railway network and its buildings by 2035.
