Did any West Coast Main Line InterCity trains ever call at Bletchley or Northampton before Milton Keynes Central station opened in 1982? Or were they all non-stop from at least Watford Junction to Rugby until that time?
In some ways it would surely have made sense to have at least a few IC trains calling at either Bletchley or Northampton (particularly Bletchley as trains avoiding Northampton and running via Weedon also pass through there), as either of them but especially Bletchley could have served as a distribution centre for the same sort of area that Milton Keynes Central did (and still does) once it opened.
