The UIC ERTMS Atlas was published for the first time in 2007, with a second version issued in 2009.
This atlas is the result of a joint venture between UIC and UNIFE aiming to merge the UIC ERTMS database with the UNIFE ERTMS database to avoid inaccuracies and provide a more realistic representation of ERTMS and ETCS equipment throughout the world.
Since 2009 UIC has been managing an ERTMS database with all the data on ERTMS lines and ETCS trains currently in commercial service, subject to pilot tests, under construction, contracted out or at the planning stage across the world.
