CSX was in the process of purchasing a bunch of re-manufactured SD40-2s from Morrison Knudsen in 1990. In October of that year, one of the "new" units is on the point of a southbound coal train at Twin Tunnels, at Hill Station, VA. This shot would leave one with the impression I was standing inside the tunnel. Of course not! This was shot from the south portal with an old Vivatar 70-150 zoom lens I used for years. The window of daylight here is quite brief, so it's sometimes difficult to get a train to show up when the light is perfect. This day, I got lucky.
