I'm trying to learn about Hl signals (I figured if I get a head start before Matt's tutorial then I'll follow it better. Also been brushing up on KS and HP). Hl 1 apparently means max line speed. Is it just a yellow light near the bottom, with no bar of lights under it, or something different? Thanks.
Wooo. Thanks for that, lots of info there Hl 1 looks to be a green distant signal and nothing for the main signal then (but there's 4 aspects which can mean line-speed, depending on what happens next). Thanks.
