Reaching back a long time, Dad would have been about 5 years old when the Milwaukee Rail came through Danvers.  They had to build a trestle over several streams, one of the longest/tallest being over Sage Creek, which was pretty much in Dad's back yard.  Additionally, they had to dig a tunnel between Danvers and Hoosac.  He remembered going to the work camp in the evening, where a number of folks from the community would gather up all of the uneaten pies and food that the camp had left over, which sounded like it was substantial.  Must have been quite an operation to construct all of that.  I came across this picture on a site called smokstak.com, (I'm sure Gary is familiar with it), of the trestle being built. The caption states: "This is a great photo I own of the construction of the steel trestle over Sage Creek in Montana's Judith Basin, on the Milwaukee Railroad's new line from Lewistown to Great Falls in 1913. There is a locomotive providing steam as well as a donkey engine up high on the equipment providing winch lines for erecting the pillars onto the concrete pads below."  Kind of a neat picture.
Rob Biggs: Google maps has a pretty good shot of the tressel, you can see each concrete pillar it sits on, and the shadow of the tressel shows on the ground. How long was the tunnel!?? I found it on Google Maps as well, It looks like its a long one, maybe 1,500 feet or more??

"The Sage Creek Trestle is the last and longest of the trestles on the way to Denton. It is a 27-span Trestle, 163 feet [50m] high and 1,698 feet [518m] long. The 1996 movie Broken Arrow filmed dangerous train sequences on the Sage Creek Trestle in 1995 with a 150-person crew over six weeks. The 2,014-foot [614m] Sage Creek Tunnel nearby is 300 feet [91m] underground." [MontanaCowboyFame]

Treasure State Lifestyles Montana posted three photos with the comment: "The Hoosac Tunnel near Denton, Montana was built in 1912-1913. The 2,014 foot [614m] tunnel is 300 feet [91m] underground and the Charlie Russell Chew Choo goes thru this tunnel."

I easily found the trestle and tunnel with this map.

When I noticed that the route still has tracks, I checked if BNSF owns this route. It does. I traced the route on Google Maps from Judith Gap near the middle of this excerpt north to this trestle and tunnel. A comment on a post of the Indian Creek Trestle says that this route is also operated by Central Montana. Those notes on the Judith and Indian Creek Trestles also describe a tourist train railroad that uses this route.
