Railway service road between Machadadorp and Waterval Boven

[Gert_GS_650]

If I look on on Google maps I can make out a road leading in the direction of the railway that leaving from Machadadorp and can see it for a while . I can make out remains of a road close to Waterval Boven as well
Now my question is , next to the railway is there a complete service road ?

Help would be appreciated ( trying to avoid the tollgate hahaha )
