Manchester Picadilly (wild guess)
Really!Correct, I would have also accepted Manchester London Road...
Really!
Okay, here's my one:
I have three platforms, with routes leading in three directions; one of the platforms can only be accessed by a line that has a 1/2 hourly service most of the day. I also have a direct service to London.
Nope, too close to London.
Greenford fits.
NopeStill fits.
A disambiguation clue is needed.
Lichfield TV if the route north is discounted as not normally having a service?
NopeAs does Selby tbh.
Correct, it is St. Erth.
Somewhere like Stourbridge Town - but that hasn't closed and reopened.
Marlow??
