I’ve always been a fan of restoring rail connections between the Lehigh Valley and NYC and Philadelphia, but it’s worth revisiting why we might want this.
Basically if you’re going to waste this very expensive infrastructure on Park n’ Rides, then it’s not worth doing. Simply grafting passenger rail onto the existing transportation and development mix in the Lehigh Valley would be an enormous waste of money. But if you’re going to use this as a catalyst to build out. intra-regional bus rapid transit, increase residential and commercial density near rail stations, and generally attempt to ratchet down mode share for private cars, then it is probably worth doing.
Rail doesn’t lose money – low-density land uses like Park n’ Ride development lose money for rail by undermining ridership and high-intensity development around stations.
