Services between Jægersborg - Svanemøllen and Ryparken - Klampenborg will be replaced by buses over the weekend while the tests take place. Commercial CBTC operation will begin on the two sections in May.

This follows the introduction of CBTC on the Jægersborg - Hillerød section of the network in 2016.

Following the installation of CBTC, the maximum line speed will be increased from 100km/h to 120km/h with headway reduced from 2.5 minutes to 1.5 minutes.
