Moving Block CBTC may be a bit extreme as a proposed train protection system onto an existing mixed traffic railway. Consider real world examples where ATP is being put onto mixed traffic lines eg ETCS level 1 type ATP systems using existing lineside signals (eg NSW), or ETCS level 2 type ATP systems (eg Thameslink,) with cab signalling for the ATP area and retaining lineside signals outside of this area.
