Limbo/UP/D&RGW Tennessee Pass Tunnel North of Leadville, CO

I labeled this route as "Limbo" because someone wanted to buy it, but UP refused to sell it even though they have designated it as out of service. This route was made obsolete by the Moffat Tunnel.

Earle Kittleman: This is on the Minturn side. Correct?
[Minturn is a town that is north of the pass.]
Denver and Rio Grande Western Railroad shared with the comment: "A spectacular shot."
Tim Fornstrom: Cool. A friend ran helpers out of Minturn until they closed Tennessee Pass. He's an engineer on the California Zephyr now. I was in Vail on a ski trip and took a day to chase trains on the pass not long before it was shut down.

No, that goes straight into a left hand curve as you leave the tunnel.

Note how US-24 was able to climb up along the side of a mountain on the south side of the pass but had to wiggle back and forth to quickly descend into the Piney Creek Valley.

I had to zoom way out to determine the timetable (east/west) directions.
