Dan Onorato has the right idea ("Onorato Eyes Rail Links to Airport," April 29). There's a better way to get to the airport via rail, but it has to originate at Station Square using the former Pittsburgh & Lake Erie right of way going west to the former Montour Railroad right of way that leads to the Montour interchange of the Parkway West.
New rail and roadbed would have to be constructed from the parkway interchange west to the airport. I think it would be more economical to use existing roadbed where available. But then, if federal funding is involved economics is not an issue.
