Hoekse Line conversion
RET Metro Line B is an east-west Metro service for the City of Rotterdam conurbation. Prior to 2019, Line B service operated between the eastern terminus in Nesselande and Schiedam Centrum station located west of the city center. This original segment utilizes both overhead wire and third rail for current collection and has a section at the northeastern end of the route that includes level intersections with streets.
In 2019, an extention of Line B opened between Schiedam Centrum Station and Hoek Van Holland Haven Station. Like Metro Line E, the Hoekse Line was converted from a conventional railroad service to metro operations. This service employs an overhead power supply system and level intersections with streets along the route. New rolling stock was ordered for this service. The Line B extention is compatible with the existing infrastructure of the Rotterdam Metro.
