Railserve,
I have thought that fares on the Keystone service line were comparatively a bit cheaper than those on the main NEC.
I don't think, however that this so-called "high-speed rail" will be another Acela Express corridor. I'd expect simply the "regional" equipment to be able to travel at higher speeds. I mean, Metroliners have done better than 100 mph, so the same would be expected of conventional equipment hauled by AEM-7's or HHP-8's on the improved track, right?
