tunnels even though only two are in use. There is a stub tunnel at North Sydney railway station, north of platform 2, for a never constructed Manly to Mona Vale line. From the top of the northern stairs to platform 10 at Redfern station it is possible to view the unfinished structure for the low-level "up" (toward Central) Southern Suburbs platforms. The associated never-used tunnels are quite complex. Immediately to the left is the (surface level) stub tunnel for the "down" Southern Suburbs track. This short tunnel exits on the northern side of Lawson Street road bridge. There are at least nine railway tunnels under the suburb of Redfern: some in use, some never used. Platforms 26 and 27 at Central lie above the Eastern Suburbs Railway platforms and have never been used for trains. Like St. James station, these stations have stub tunnels, although they are much shorter. There are three tunnels for the old Pyrmont goods line, not part of the passenger railway system. One runs underneath Railway Square, near the Central station railway yards. For a time, the line was used to service the Powerhouse Museum. The corridor adjacent to the tunnel is now a pedestrian pathway, the tunnel itself is disused. The second tunnel runs underneath Glebe and is now part of the Dulwich Hill light rail line from Central station (see Metropolitan Goods railway line). The third tunnel was created in 2000 when an extension to the City West Link Road through Leichhardt was built on top of a cutting. This is also now used by the light rail.
