Swedish railway signalling

The interpretation of the signals follow the ERTMS level 1 standard, but the actual look is national.This meant that freight trains Oslo–Narvik passed Hallsberg southeast of Oslo until the shortcut Kil–Ställdalen was upgraded to ATC in 2017.European Rail Traffic Management System(ERTMS/ETCS) has been introduced on a few railways in Sweden such as Botniabanan where it is actively being used.Mainly ERTMS level 2 is used, in which basically no light signals exist and all messages are shown on a display in the driver's compartment of the train.They are divided into three categories, A where the signal showed stop even before the process, which may be due to the driver, failure of the train brakes, slipping and more, category B, where the signal was inadvertently set to stop due to technical error or mistake of the signalman, and category C, where the signal was intentionally stopped, for example due to a sudden danger such as a car at a level crossing.
