(COA May 2016)
The first test started at the MILE 0 marker at Langley. We found the following distances in-scale miles:
Mile 0 to end of yard lead is .9 miles
Mile 0 to the end of Croaker is 1.4 Miles
Mile 0 to Thornburg is 2.1 Miles
Mile 0 to Rapidan is 2.5 miles
Mile 0 to Columbia Furnace switch (west End) 3.0 miles
Mile 0 to Shenandoah is 4.1 miles
Mile 0 to Tunnel switch is 6.3 miles
Mile 0 to Helper is 7.2 miles
Mile 0 to Mingo is 11 miles
Mile 0 to Nitro is 12.9 miles
Mile 0 to 14.2 miles
(NOTE: This is not the complete loop)
From the red ball to mile 0 which runs through the turnaround in the helix is 14.5 miles. This creates a total loop of 28.7 miles, or a one way trip of the layout of 14.35 scale miles. One scale mile is 70 feet long. At this, the main line would be 1004.5 feet.
Double track main from Main 0 to Rapidan is 4.1 miles 287 feet.
Single track from Rapidan to Shenandoah would be 1.6 miles 112 feet.
Double track from Shenandoah to Tunnel switch would be 2.2 miles or 154 feet
Single track from Tunnel switch to Helper is .9 miles or 63 feet
Double track from Helper to red ball would be 490 feet
Total track on the main line both lines equals 2037 lin. Feet
