They can get to Heathrow Airport via a junction near Acton Main Line Station and just follow the GWML to Airport Junction and the service I would do is from Bedford so they can call at Flitwick, Harlington, Luton and St Albans CityCould they? How would the trains get to Heathrow? And which MML stations would they serve?
(Hint: there’s a reason the service is planned to go WestHampstead or Brent Cross to Hounslow)
