Line M1 (Rijndam)
Panbos - Molenwijk
The line runs above-ground from Molenwijk to Simvlietlaan and from Nobelplein to Panbos. Between Simvlietlaan and Nobelplein, line M1 runs underground.
The section from Nobelplein to Panbos was once a local railwayline, starting at Rijndam Noorderpoort. A few years ago, the Rijndam city council has decided to connect this railway to the metro network. This was done to eliminate the need for passenger interchange, to increase the frequency of services on the line, and to allow for the demolition and redevelopment of the site of the former train station. Power on this section is supplied by overhead wires; at Nobelplein, line M1 trains switch from 3rd rail to overhead power supply and from ATB to ZUB train protection. Between Noordvliet and Panbos, the line runs on a single track.
