The route of this group of caches brings you over the Royal National Park Line which was a railway from Loftus to the National Park Station between 1886 - 1991.
On Wednesday and Sunday, the Sydney Tram Museum currently runs an electric tram between Loftus and the old Royal National Park station. The trip goes from the museum over the Princes Highway past this railway crossing and two sheds and then to the old railway station platform. See http://www.sydneytramwaymuseum.com.au/ for more details on the tram museum.
When you are here, take notice of the number on the last pole (VWX). Then count the number of benches on the platform (Y). Find a pole with white text in a red background, count the number of letters (Z).
To find the cache, you will need an origin, a direction and a distance.
The origin is the FCth stand of the sun roofs from the Loftus direction or the Sth stand of the sun roofs from the end-of-the-line direction.
The direction is the cardinal direction which is not on the pole with the white text in the red background. (the text is getting unreadable, it is "terminus")
And the distance is (10 * U) + (I + K + M + O + L) meters.
