There is a manually operated set of double-slip points in Hornsby Car Sidings And correcting my previous post: There is currently 4 double-slip and 4 single-slip points in Hornsby Yard. There used to be a 5th double-slip into the down yard. This set was removed about 10 years ago. The current number will be reduced to 1 double and 3 single after October Stage 1 of the yard remodelling
