Wye in a loop

[MountainMan]

There is no wye. The crossing trail is just that, a vehicle path, and there are no turnouts or track in that image to make a wye out of anything, just a loop that is clearly delineated. Expand the image and you'll see it more clearly.

I have to agree. Expanding the image clearly shows only a loop, with no other tracks, or turnouts.

Could there have been a wye there at one time? Maybe, but then again, would a railroad go through the expense of removing the now unused track? The photo clearly shows no "unused track".
Could a wye have been replaced with a loop? That is a possibility, in that a loop turns a train more efficiently than a wye, and there is, what appears to have been, where a wye might have existed. Clearly though, only a loop exists there now.
Geographically this is in Glacier National Park, in Northwest Montana. near the town of Summit, about thirty miles East of Kalispell

Yep, and it's replicated there exactly on the train sim software I run, right at that location. In the sim, it's mainly used for helper sets.
