HI re3, and welcome to our forum.

Philip's link gives plenty of data, BUT... this seems to be an Indian website. Although it's based on UK signalling principles, there are some differences. So be wary.

For UK-specific practice, you should read the RSSB publication "Signals, Handsignals, Indicators and Signs Handbook RS521". Which can be found at this link....https://www.rssb.co.uk/standards-catalogue/CatalogueItem/RS521-Iss-6

If you want an interpretation or explanation of anything you read there, just ask us. Of course, the more specific your question - the more precise the answer will be.

W.r.t an explanation of Approach Control at junctions, the purpose is firstly to advise the driver that they're being turned onto a slower route (either with a junction indicator, or on faster turnouts with flashing yellows), and secondly to get them to reduce speed to that required for the turnout.

The key to driving these arrangements is to NOT EXPECT the red at the far end to clear. The driver must keep bringing their speed down with a view to stopping at the red. If the signals STEP UP, then great - you're up and away. If they don't, it doesn't matter because you're expecting to stop anyway.

The junction indicator only tells you that you're taking the diverging route. It doesn't guarantee that you have the road all the way through.

HTH, John
