Wheeling and Lake Erie coke train from Mingo Junction with Follansbee coke heads west in a very secluded part of the former Pittsburgh and West Virginia main line. The train has just punched out of the first of two tunnels in the distance of a thousand feet.
This was a 20 minutes hike down to the main and a 30 minute hike back out. Why, its all uphill going out.
No need to fear, Im not in the tunnel. This was done with a 300MM.
