The east end of Allentown Yard is CP88 (Bethlehem) and Bound Brook is MP 33, so we're talking 55 miles. If a train is sent straight through, I would guess 70-90 minutes. The Lehigh Line has sections of single track, so a meet at any point could put a train into a siding, thus increasing travel time.
