I know this is anathema to a lot of people on here, but I really wish there was a real search of some kind. I’m looking for people posting about niche stuff and it’s too damn hard!

If you post about train control, especially CBTC, hi.

@xferok I'm going to poke @q @hopla @rail and @jon as people interesting in trains, in various ways.

I don't think I've seen any post about "CBTC" but there's definitely some expertise around trains in there.

@Sobex @xferok @hopla @rail @jon I know a non zero amount of random facts about CBTC/ERTMS, but by no means an expert
@q Sorry but I know sod all about CBTC. I know a bit more about ETCS! @Sobex @xferok @hopla @rail

@jon @q @xferok @hopla @rail

What does CBTC stand for, and what does it refer to, btw ? (Sounds like it is signalling related, but I can't place it)

@Sobex @q @xferok @hopla @rail Communications-based train control. But mostly used for metros. And despite the rather generic name it is a standard. And the standard does have *some* things in common with how ETCS works.
@jon @Sobex @xferok @hopla @rail but there are a few different CBTCs which are ofc not interoperable
