That day service train to NY is planned under both the NY and PA state rail plans It's to fill in the service gap. I'm not proposing high speed rail but corridor service with dedicated passenger tracks alongside existing freight rail lines with increased speeds up to 110mph. The Amtrak 2035 Plan and most state plans do not have high speed rail in them at least not above 125mph. The focus is on improving and expand corridor services which are more popular and easier to build. Under the 125mph upstate ny empire upgrade you would see end to end travel times be reduced by 4hrs down to 5hrs from NY to Niagara Falls and 6hrs to Erie,PA. There's also a separate study underway for the southern tier region of NY so Erie might a few more trains from NY by 2035. Most of the Main Lines in PA were built for speed so re-installing a second track and upgrading it wouldn't be hard. You wouldn't need to take land or do any serious infrastructure work in most cases.
