Mud Tunnel
Here are two shots taken at Mud Tunnel on the Chesapeake & Ohio. This spot is just west of Covington, Virginia. We first see a westbound freight and then the eastbound Amtrak James Whitcomb Riley powered by a General Electric P30CH.
Update: someone on FB tells me this locomotive was destroyed later in 1977 when it struck a logging truck near Florence, SC.
Two images by Richard Koenig; taken March 23rd 1977.
