Hi,
I was going through the past papers of module 3. At a glance on warner route, the aspect sequence has just Y - > R.
I understand that when warner route is set and not stepped up, there can only be yellow aspect on the entrance signal with restricted approach release condition.
When cross referenced with Network Rail standard 11201 A18(Erratum) & 8003 series standard, observed that the warner class routes are shown with full aspects just like the main signal aspects. Is it because the warner route steps up to main route and so full aspects are shown.
My doubt is how the principle tester tests the warner route if we show all the full aspects? if not stepped up, how can he check the other aspects, if we show all the aspects that the signal has?
Thank You.
