Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

AFB is a separate, overlaid automatic train operation (ATO) system. In theory you can overlay an ATO with ETCS, too

Forgot to note the drawback: of course, it remains yet to be developed. For that reason, for example, London's Crossrail will be equipped with standard metro CBTC with ATO overlay on the central tunnel section, while trains will also have ETCS L2 and British TPWS for the connecting sections.

As an overall comment, while I am also generally negative about ETRTMS and especially ETCS L2, now that the rollout progressed in some countries, it would be nice if at least all mainlines with significant through traffic on networks with magnet-based (intermittent) train control systems (like Germany) would be switched to ETCS L1.
