fast junction signal
An alternate method of signalling fast turnouts was introduced in NSW, for locations where the straight and diverging routes are the same speed, or only vary by 5-10 km/h. Normal main (straight) indications are displayed for both routes in conjunction with a route indicator at the junction and a turnout repeater on the signal in the rear.
Approaching Hornsby, HY17 signal on the down main displays clear with the route set for the down relief line (the turnout is out of sight around the curve). The line speed at the turnout is 80 km/h for the main, 75 km/h for the turnout onto the relief line.
