What other example of Rail Replacement bus/coach services which are quicker ?PL-4 is the Acton Town to Rayners Lane service which does not use the M4. Is this the PL-3 that you are referring to, which does Hammersmith non-stop to Heathrow T23 via the M4? It normally uses coaches but red buses have not been strangers to the run.
It's one of very few rail replacement services I know of that's actually faster than the train it is replacing!
