There are no real heritage units. They were photoshopped, and the whole roundhouse thing was faked with 1/4 size models on a sound stage. Doesn't count until I see one, and I live on CSX tracks, so even if they were real, I'd never get to see one.</jealousy>
NS 1073 (Penn Central) passed my quarters in Topton going east about 10 hours ago; we get about thirty moves a day through here, but that's my only NS sighting to date.
Actually, it;s probably easier to catch the CP units in D&H paint at my "second home" along the former PRR Sunbury Line, since the D&H units seem to stay close to their would-be home rails.
