The Shenandoah Valley and Ohio Railroad was planned to construct a rail line from Orange, the western terminus of the PF&P, across Swift Run Gap into the Shenandoah Valley. The total cost of the 93-mile-long Shenandoah Valley and Ohio Railroad was projected to be $970,500, including depots and sidings. The PF&P's track was narrow gauged to and was extended to Orange by early 1877, a distance of 38 miles from Fredericksburg, the eastern terminus of the line. The use of narrow gauge instead of standard gauge allowed for a savings of 40%, and because of this, the company switched the original plans for the Shenandoah Valley and Ohio Railroad from standard gauge to the more cost-effective narrow gauge. Although the Royal Land Company had planned to extend the line from Mathias' Point (27 miles east of Fredericksburg on the Potomac River) to somewhere near Harrisonburg, Virginia, it failed to build beyond Orange to the west and Fredericksburg to the east. The cost of the 38-mile section that was actually constructed was $956,425.83, and since the Shenandoah Valley and Ohio Railroad never came to fruition, its projected costs were not realized.
