The Swiss Alps are unique in railway geography: busy trans-European corridors pass it on spectacular lines, while a network of scenic narrow-gauge railways transport within it.
But, they weren't always unique: the Colorado Rockies used to have a similar infrastructure - only bigger & higher1. The 3-4 lines still used in revenue service and half a dozen tourist lines are but a faint reminder of what was. One of the two forgotten spectacles I'll focus on was the line across Hagerman Pass:
(Editor's note: there'll be a couple of links below to earlier contributions of an ET commenter from Colorado we all know, who I hope can contribute even more and correct eventual errors. Others are welcome to 'comment' with any forgotten or mountain railway anywhere!)
Forgotten Transcontinentals
The USA was crossed by six "full" transcontinental railroads, but several other companies took part and fell short in the race to the Pacific - ending up as branchlines or worse. Colorado had three of these, all climbing above 10,000 feet (and 3000 m).
The least lucky of them was the Colorado Midland. Rivals having taken river valleys first, it had to climb three very high passes in succession (asdf showed us a bridge on the first climb) - then was forced to share tracks on the rest of the route to Salt Lake City...
The worst, Hagerman Pass, was the third - crossed initially in the short Hagerman Tunnel at 11,528-feet (3514 m), with switchbacks and loops on trestles on the climb (another old photo). Extreme snowfall and grades were battled 1887-93, then the longer Busk-Ivanhoe Tunnel, built2 among incredible hardships, opened a safer route. In winter 1898/9, the old line was re-used during a financial dispute... This railroad struggled on until WWI, when the military was given control over railroads - and closed it.
The two other failed transcontinentals (the still known Rio Grande, and the Denver & Salt Lake - the latter never reached the destination in its name) ended up in common ownership, and half of each was connected into a straight and better-built route still existing today3.
As a prelude to this upgrade, North America's highest railroad pass, the onetime D&SL route across Rollins Pass (ex Corona Pass, 11,671 feet/3557.3 m, climbed with some spectacular 360-degree loops), was replaced in 1928 by the then longest (today still fourth longest) North American rail tunnel: the 6.21 mile (9996 m) Moffat Tunnel (also see via asdf again).
Forgotten Narrow Gauge
What would have become the North American railroad reaching the highest altitude4 was the Argentine Central, west of Denver. Begun 100 years ago, it climbed up a steep mountainside with 7 switchbacks (first 2 above connecting railroad's double loop), but then construction ended half-way due to WWI. Tracks ended abruptly just below a nondescript bulge on a ridge - the 13,117 feet (3998 m) Argentine Peak5:
(more B&W photos) Before the line closed during the next World War, there were direct coaches from Denver - tough, traversing tracks of three successive railroad companies, it had to be handed over twice... Nothing remains of either, but just below what was the Argentine Central, a spectacular section was rebuilt 1973-84: the Georgetown Loop RR (old postcard).
