PATH to Newark/ Liberty Airport?

Question

Has there ever been any study, serious or otherwise, to extend the PATH from Newark Penn Station out to the Newark / Liberty Airport Rail Station ? Mayor Bloomberg, among others, have mentioned it over the years.
Any Suggestions on an intermediate stop ?
How about South Street/Mulberry Street ?
Wasn't there a South Street stop on the Penn RR ?

Answer 1

Been a Jersey rail fan for many years- I never heard of the details your speaking of clearly..There's only two option that I know of being the light rail and the secaucus jnct. either way is a pain in the uknow! Unfortunatly there is only the new tunnel on the minds of the politicians.. Again too much+too late!
