I'm not sure that is an ORCATS raid in my understanding, though I agree the definition is debatable.
One good example to me is the old FNW Manchester to London service. This was very much a budget service (£13.20 "Anytime Return" with a Railcard, even in 1998 money rather good), but also had a First Class section which was just regular Class 158 seats with antimacassars. This was arguably an ORCATS raid - nobody would pay for a First Class fare as it had no benefit at all (the trains were far from overcrowded), but it would get them a small share of Any Permitted First Class revenue.
Another example is Open Access operators stopping at a main station (like, say, GC at York) on the way to London to get a share of Any Permitted fares for that flow even though almost nobody will actually use the service as it's slower than the main TOC. I've long wondered why OA operators are allowed to be part of the
Without wanting to go too OT, I'm not sure how much of an "ORCATS raid" the FNW services were - they didn't have the equivalent of a York or Donny stop. For example, the Manchester Airport service called Alderley Edge, Sandbach, Tamworth (for pathing) and Watford (pick-up/set down). No real railheads, other than the odd passenger who would've otherwise connected at Crewe. And the first southbound arrivals at Euston weren't until around 1000 or so (at least from Manchester Airport - first departure was about 0619).
Similarly, the Blackpool service omitted Preston and Wigan and only called at Warrington (non-passenger) to attach to the Rochdale portion.
