So where is it

[MegaStationMan]

Ive searched as far as I can think but I cant find the graphics that show a blue light on the signals when you've set a restricted route or other rules on that signal (obv an nightly alpha build of the patch).

So where can I get the graphics turned on?

You'll need that GRF, as it contains the new graphics...
